It's an irrelevent question, you don't really get the abillity to pick.
Ignoring the whole Mitachlorians thing, it's important to understand that Star Wars is based around a cycle. It's really a pretty grim concept when you get down to it.
The idea is that good and evil get turns controlling reality. Once one side has dominated long enough The Force itself engineers a change, leading to a brief period of balance and chaos, and then ending with the other side taking over for a few thousand years.
So basically what happened was you had a period where The Sith had an empire and were mostly dominant, then they got wiped out by the Jedi, and then we saw a Republic rule the galaxy in relative peace and harmony for a few thousand years. Then as the movies pick up you wind up with this prophecy that Anakin is going to bring balance to The Force. Well, when the universe is working fine, and the good guys are in charge the only place to go for balance is "Down". The Empire was simply the tool used to re-assemble everything into a balanced form.
I think George Lucas danced around the idea of ever doing sequels himself "officially" because in the end they would be very downbeat.
The reason why the Sith are so tough in the movies is because the universe is literally on their side, and ordaining their victory for the most part. You'll notice all the good guys are talking about how the force is cloudy and such, that's because their powers are waning while the other side comes in to replace them.
Pretty much things were supposed to have happened to the Sith in reverse. Time for balance, their powers become "cloudy" and then you have a handfull of Jedi start wiping the floor with them and painthing the cellings with their guts. The Sith having been so completly wiped out in the battles that thousands of years later nobody even knew what one was for sure.
George Lucas had something of a say in the development of the Knights Of The Old Republic games plotwise. Despite having not been finished properly (as any fan can tell you) Knights Of The Old Republic kind of explained it the best. In that storyline Kreia is attempting to end the cycle and ultimatly give people freedom from The Force, by destroying The Force itself and all of it's champions on both sides. On a lot of levels, as messed up as she is, she's arguably one of the more "heroic" characters in her own way than anyone else in Star Wars as her actions simply mattered more when it comes to fate.
Having not been properly finished the exact details of how she planned to kill The Force itself was kind of glossed over, though she DID do quite a job on both the Jedi and Sith when you get down to it.
The point of this is that in general one does not really just go walking in and sign up to be a real Sith or Jedi. The universe chooses you, whether that's due to mitochlorians or whatever else. If you try and sign up you wind up becoming like one of the Republic Footsoldiers, or one of the Sith minion-soldiers that die in droves. In the end I'd say that's as much as matter of where your born and your culture than anything. What role your given to play is dependant on what the universe decides is supposed to be happening. If it's in the midst of a light or dark cycle your only going to see light or dark Jedi. Towards the transition periods your going to see both, but ending with the destruction of the faction that was previously in charge, with little they can do about it.
While not popular, or well acted, this was a big point about Anakin in the Star Wars prequels. The guy was really messed up because he wanted to be a good guy, but the universe had a job for him and just kept pushing. Things like what happened to his mother (causing him to go into a rage on the Sand People) being key elements for this reason.
This is also why guys like Obi-Wan were so confused about the prophecy. Obi-Wan thought he was supposed to be a savior, but by "balance" that actually made him like The Anti-Christ given that the only place for the good guys to go was down (some of the final comments after their show down). Obi-Wan's victory actually being the final thing that drives Anakin into becoming evil.
The "Redemption" of Vader largely being to get rid of the Empire. The idea being to create the period of "balance" first because that is how it worked. If The Empire survived as it was it would have been an instant transition. When he tossed Papaltine into the core he was balancing the tables between the Alliance and Empire Remnants.
Well enough rambling, the point is that "would you be a Jedi or Sith" isn't a valid question since you don't get to pick it, instead your chosen for the most part.
The big thing I think is borked about the whole concept though is that Jedi are supposed to be forbidden to love. Love being defined as a "bad" thing. I don't know maybe it's supposed to be a Yin Yang analogy (balanced sides, but they both have a piece of the other in them. Sith having their good via love, and the Jedi having their evil by forbidding love).
Given the option I choose to be a heavily Gimmicked Bounty Hunter with more brains than either Boba or Jango: I start carrying a fully automatic contact grenade launcher. That way if someone decides to get cute with a light saber the grenades blow up on the blade as they deflect them taking the goober out. If they choose to go "look at meeee I'm Force Powered Spider Man" and start jumping all over the place, I've got that juicy area effect. Plus I can always load image-seeking RPGs, concussion bombs, or fragmentation rounds (gogo shrapnel clouds).
Also then instead of being one of those dorks who futilely shoots a blaster ineffectively as a ship takes off in front of them, I can switch over to a clip of more focused AP grenades and actually do some damage. >
I mean honestly, what the heck is it with the blasters at this tech level. Does everyone intentionally use weapons that seem to blow chips specifically so the Jedi can look cool in comparison? For some of those fights shooting at Jedi you'd think someone would have the brains to load a few Battle Droids with gatling guns, or have it carry the equivilent of a bloody M-16 or something. Sure you can block one blaster bolt at a time fired semi-auto but try blocking like 30 projectiles in a couple of seconds that you CAN'T see.
Oh I'd be a more or less good guy, don't get me wrong (unlike the ones in the canon for th emost part), but I wouldn't have to worry about whether it's right to love or not, or get into the whole Force Drama thing. I could have my own little astroid mansion hideout from my uber-bounty monies where I can retire if the wrong side happens to transition into power while I'm around (well maybe, the thing is nobody understood the cycles except Kriea).
Apologies for the rambling. I wonder if anyone reads some of these huge walls of text I churn out when I get moving.
