I think he is the most technical and adept player they have ever had, but as with so many geniuses that can play anything he suffers from not having his own distinct style and becomes a bit anonymous. He is also the type of player than needs a band as a vehicle to promote his artistry to the full extent.
I think the problem really is that we've not yet heard any GN'R songs which he's helped to write (Mainly because they've yet to actually write any songs since he joined, apparantly), so he's only been able to make additions to songs written by the guys before him, hence why he's yet to establish a real 'style' within the band.
However his dedication to the fans is second to none. I remember not too long back he had a live chat on his forum (myself and captain took part), and he used to do all those meet n' greets last year.
Fuck, even at Reading festival last year where I was at, the band were late and Ron came up on stage and spoke something into the mike, from what I heard he was talking to Axl/the rest of the band telling them to get their arses on stage.
Though DJ fortunately is also vey fan-friendly, to be fair to him
