I have two friends that both have PRS Customs and while they look great, to me they both sounded very anemic. It wasn't just in my hands, they both have completely different styles and rigs, and both guitars were meh? Now I realize that players make guitars and not the other way around, but I haven't seen any videos of guitar players using them that made me say WOW.
To answer the OP's question, if you're looking for a versatile cover band guitar, a super strat is probably your best answer. Having done the casino circuit for a few years, you're going to need a handful of guitars anyway, for the different tunings and backups. The reality is, the audience could give two shits what you're playing or how close the "tone" is to the original. Most cover bands are playing with way too much distortion for the songs that they're covering any way, which further obscures the sound of the guitar.
