The bebot solo is my least favorite that I can remember. It just doesn't fit the song at all, in my opinion. JR's solo's in the main instrumental section of ANTR are very hit-or-miss, and seem to sound like a mix of random shredding with brief moments of fluidity and purpose.
As far as a guitar solo, right now I'd have to say the one from On The Backs Of Angels. It's very "average JP" in the way it's structured. The part directly after the solo is one of my favorite moments on that whole album, but the solo itself makes me feel like I've heard it before. I wouldn't even call it weak, just average.
