JP is #1 for me too, and even more #1 when he is along a pianist like rudess (for more style exploration and creativity).
He riffs from trashy to popy
He masters every technique, people said he is weaker sweeping, I'm not sure, but on the other hand he can play so fast...
His inspirations comes from classical type arpeggiating to neoclassical tremolo picking and legato, plus prog, hard rock, jazzy chords sometimes...
The words complete musician couldn't be more true, it feels like he absorbed good traits of most iconic guitarists, added to a great touch and music theory.
The only complain I can understand is that some people feels like things are too processed and nicely done, making the reputation of "robotic" playing with less feeling.
But once you're touched by several moments of grace, it's less a thing.
Too much is the ennemy of good, but some of us can handle too much
