Go with the JPXI if you want to pretend you're Petrucci,
Go with the Caparison if you want to play guitar.
Really, this is one of the stupidest posts I've ever seen on here.
The JP is a fantastic guitar, as many people here would attest. They are versatile, beautifully-built, well-designed, functional and none of the models scream "Petrucci", you can quite easily play one without looking like a fanboy... more than can be said for almost any other metal artist's signature guitars.
Caparisons are overpriced. I've never played one so I can't comment on that side of things, but I've played several EBMM JPs (and I own one of the cheaper Sterling JP100s) so can vouch for the fact that they're wonderful guitars that cost significantly less than Capas in most cases (unless you go for a BFR...)
I hear great things about Caparison and would love to play a couple some day, but the JP is so much more than a Petrucci fanboy's expensive plaything.
I think you need to take your head out of your backside and play a JP before making retarded comments like this on a public forum...
