It's starting to get apparent you didn't play the game for very long at all, but we'll leave that. I chose those two Rifles and those two SMGs because I use all of them, depending on the occasion. There's no way you could say any of them are flat out better than any other. You picked up that recoil reduction is difficult to quantify (the Torgue happens to have much better recoil than that Vladof), here's a few more: bullet velocity (explosive and E-tech weapons have lowered velocity), bullet trajectory (the Lascaux has a horizontally biased spread), blast effect (esp. concerning the Torgue), burst fire count (both Dahl's fire in bursts while scoped, but for different counts), scopes (different zoom ranges, and even just different aesthetics). We'll ignore the elemental effects, because you wouldn't know about those.
You also picked up that different weapon types had different ranges associated with them (e.g. a Sniper Rifle has a different effective range to a Shotgun). What you may not appreciate is that different versions of the same weapon type can still have very different effective ranges. Of those two Rifles, the Torgue is more stable when scoped, so it's a bit better at long range provided the target isn't moving too quickly (due to the lower velocity). At medium range things tend to move around a bit quicker, so the Vladof's higher velocity is more appropriate (and the harsher recoil isn't as much of a problem). At point blank, only the Torgue has a workable hip-fire (the Vladof is all over the place), and because it's got a small blast effect you can fire it at a mobs feet as you retreat. So it's a bit like long range = Torgue, mid range = Vladof, short range = Torgue. The SMGs, even though they're the same manufacturer (with the same mechanic, which is the burst fire), they're totally different. The unique spread on the Lascaux makes it unusable at anything other than short range, while the Plasma Caster can snipe in little bursts at mid-range if need be (you'd still use it over the Lascaux up close if you're up against flesh, but I digress). There's also certain enemy types with convenient critical locations (e.g. Loaders have three crit spots laid horizontally), against which the Lascaux will perform massively better than expected so long as you line it up just right.
And those are some pretty ordinary weapons. That Pistol in my inventory, the bullets ricochet off walls and split into more and more pellets. You can fire it round corners, or shoot at the ground in front of a mob to get better damage. My Sniper's bullets split into three that fire off like a trident. You can't quantify things like that.
So here's the crazy thing, to reiterate: that ideal you're talking about, where the players choices amount to more than just raw power, that's exactly what Borderlands does. If you'd played the game more you wouldn't be making this argument.
