My vote: Nay
Though here is my argument: In most FPS games, one of two things usually occurs. Either you play as a very specific character (Freeman or Master Chief, for example) so customization isn't really an option, or you are a very malleable character (Fallout, or to a lesser degree Bioshock) so your customization allows you to turn the game more towards your own strengths or weaknesses.
As far as appearance goes, customization in an FPS is really only for those who want to make themselves feel special. I used to play Halo 3 online quite a bit (as in hours a day) and there is only one time when I remember saying to my roomate "Man that guy's armor is badass.". For a game like Halo, armor customization is really just a pissing contest, but for a game where the armor actually has stats, why not customize?
To sum up: Custom stats = good. Custom looks = meh.
