Okay, honestly they are both versatile, but it just seems like PRS does have a wider range of endorsers. Al Di Meola, Dustie and Paul from BTBAM, Mikael Akerfeldt (Opeth), and Carlos Santana. You have your jazz, rock and Death metal covered there.
That obviously isn't a true representation of versatility, but it just seems to me that PRS can achieve a wider range of tones. No real way to test that though.
In the end, it all comes down to opinion. i will admit I have never liked the necks of Gibsons, nor the Les Paul shape. It is just boring to me. I personally love a super strat shape and ultra thin neck (a la Ibanez).
