Hey, Blakey isn't my favorite either - but I think it actually has to do with how repetitive the '60s Messengers records are IMO, not his playing. Put him with Herbie Nichols and it's like Cecil and Denis.
Nor is DeJohnette, though his playing never made me 'not' buy something.
I'm a big Han fan but I can see why his shtick annoys a lot of people. Still, his playing in the late '60s is less about that, and you can see what an excellent, hard-swinging and still very wiley drummer he could be. Those mid/late '60s Misha Quartet records give a good example, as does the New Acoustic Swing Duo and Marion Brown's Porto Novo, any of the early ICP records, etc.
