Gotta go with the 'Dog. Bobby keeps it rockin' non-stop, and I have yet to see a show that hasn't left me sweating my balls off. Just saw them in Boston on Tuesday night (yesterday, 7/10) and they were NASTY. Kimock was rippin it up, you should've heard him on Loser. In fact, I recommend going to the etree community tracker & DL'ing this one, boys. Good good show and Bobby did not dissapoint.
I love seeing Phil & Friends (esp. w/ Trey), but the ever changing line-up forces me to go with Ratdog, if not for out of sheer consistency, then for the fluidity of the jams and other misc. reasons that I can't think of right now. Just a feeling I get, I guess. Not to say I don't get that feeling with Phil, it's just different.
Phil is more spacey jam, which I love, but Ratdog gets me with the rock n' roll, jazz, and spacey jam. It's got it all.
Also, sometimes when I see Phil, some of his songs are toned down a bit, that is to say they're slower or may laid back than I'd like 'em. Also, as someone else already stated, the vocals aren't even a question. I'll take Bob all night over anyone Phil plays with.
