Pros and cons of each faction? (Specifically VS)

[lGhostl]

So NC is mainly heavy, lots of recoil but lots of firepower, lots of armor and health.
TR is mainly light, but easy to kill. Fast maneuvering and high firing rate.
VS is energy and accuracy. But energy weapons have both light and heavy? I see that the VS weapons deal less damage over a distance though. So is VS a mix between light and heavy, and their weapons get weaker over distance but are highly accurate?

Serious answers only please. I'm seriously trying to decide on a faction and I don't want a bunch of people arguing over why this faction looks dumb or VS is a bunch of crazy barbie dolls or whatever.
My playstyle is pretty light and stealthy. Some of my favorite games are games like splinter cell, and any game where I can sneak around and kill things. This is why I'm choosing infiltrator.
