very subjective question
i would wait if you are thinking of one. there is a JPX12 on the way.. and a new JP guitar (with a different shape supposedly, no real info on it yet though)
i think the neck is too thin on the 11, almost ibanez wizard (not as wide though) the stainless steel fret are nice, and the 20" radius is fantastic above fret 12 (too flat for me in the 1-9 frets range) the color is cool, and looks quite nice under stage lights.
I like the JPX nect much better, but the tone is different because of the chambering, i can't say how different though, would need to a/b them for a while.
i have a BFR, which is essentially the JP 11, but with a more comfy neck (to me) and pretty quilted maple top.
