Huh, I don't really know. Partly this is because I don't play enough true RPGs which actually have this sort of algnment system, but also because there are bits to all of them I don't agree with.
Lawful Good: I think that blindly following the letter of the law and not allowing for potentially questionable acts is just stupid. Everything is built on compromise.
Neutral Good: Probably the closest archetype I come to, and certainly whenever I write stories the heroes will be neutral good or true neutrals. I think the problem here is the Spider-Man problem, that doing only what you think is good can really really backfire on you without some sort of structure.
Chaotic Good: I barely even think this alignment exists. Acting entirely without structure will not lead anywhere. Even if you're doing good, bouncing from place to place trying your best just smacks of 'this will end badly.' Just look at Mal Reynolds, you could hardly say he's good for himself, the people he travels with, or the galaxy at large.
Lawful Neutral: See lawful good but with a massive scoop of 'I don't like utilitarianism' mixed in
True Neutral: True neutrality to me doesn't feel right, because it doesn't acknowledge good and evil. I think there are some actions which are definably evil and good, with no neutral of grey area.
Chaotic Neutral: This is like the worst parts of chaotic good and true neutral mixed together, and those are perhaps my least favourite alignments (yeah, I don't like Cap'n Jack Sparrow very much)
Blanket Statement: I never play evil characters, I can't be a bad guy, ever. I do write some complete monsters though...
Lawful Evil: Don't know much about this sort of character beyond the 'scheming visier' archetype. Not a fan. I don't like the idea in any sort of character of being constrained by a strict set of rules and regulations which hamper you from doing the right (or wrong) thing.
Neutral Evil: Probably the most dangerous of the evil types, I think that the lack of code, yet clearly defined set of goals, makes them pretty much the best sort of villain.
Chaotic Evil: Basically I see all Chaotic Evil as being basically no better than a sociopath or animal. They don't fully understand how their actions have any relation to the real world.
Mostly I play or write Good characters, and while they work within a framework, they have no problem with breaking it in order to accomplish a 'good' outcome. So probably Neutral Good with scoops of Lawful Good is the best description.
Incidentally, I hope you liked my deconstruction of the flaws of the alignement system!
