I voted for Andy (of course) and also Jonny Bridgewood because I love his bass on Boxers, Reader Meet Author, and Alma Matters. His playing is "jumpy" which reminds me a bit of Mike Mills from R.E.M. and he seems like a nice, laid back guy on that Jewel in the Crown DVD. Can't forget Gary though, with Let Me Kiss You and Tomorrow being my favorite of his bass lines.
I'd go for Rourke and Bridgewood. Rourke's compositions are insane. It's like.. his riffs wouldn't fit the songs if you'd hear he guitar and bass seperately, but in a way it's so full and amazing what he does. Songs inside of songs. His basslines are also not the easiest to play either.
Gary is really cool, but what he does is not that hard actually. Good bassist though.... just sayin'.
