All these guys have my love and admiration. Bernstein is the most likely to be found in my cd player right now, but I just spent a couple hours listening to the Grant Green BN box set. It's all great stuff.
As for Burrell, I agree, there's some nice stuff out there but he's not an especially exciting player. I'm loathe to put him down out of respect for his career though. I mean, who the hell am I? He's recorded like what, 80 albums as a leader??? But there have been times when it sounded like he was really struggling with the instrument.
