Unless youve heard Frank Zappa, then youll think its second rate shit 
Ron's music absolutely has to the same Zappa-esque sophistication, that's why a lot of other people make that association. However, his music was never meant to resemble Zappa, nor did he ever express that ambition. It's what others make of it. So try as you might to falsely imply some sort of ambition on his part.
Anyway, Zappa = Zappa and everything else = everything else. Since when is Frank Zappa the status quo? And why should any deviation from that in terms of harmonics, dynamics, rhythms, melodies, non diatonics and theory manipulation indicate anything lesser in quality? Ron is at least ten times the guitar player Zappa was. Zappa needed Vai for the (technically) unrestricted expression of his visions for guitar. Vai, according to Satriani, has deep respect for the new G3. That's how Thal, Eklundh and Govan are seen in the virtuoso scene.
If anything, Ron is the only GNR member who represents a musical force that, on its own, can hold a candle to Zappa. No other member in the past or present versions of this band brings to the table, in terms of pure musicality (composition-wise, producing, engineering, singing, playing) what Ron has to offer. Calling his vast body of solo material "second rate shit" is provocative nonsense of the highest order. Like it or not, but it's quality music nonetheless...
