Wings West or Bomex??

I'm planning on getting a new front bumper for my 98 Civic Coupe and have narrowed it down to either the Bomex bumper or the Wings West Tuner Type I. I know that both are highly reputable companies, but is one any better than the other? I know the wings west is urethane and the bomex is fiberglass. I am mainly concerned with how well they will fit. Also, being a novice in body work, I have a stupid question, do you paint the bumper before or after installation? Thanks alot...any help would be appreciated.
