well I really enjoy Hutch, gotta get some of his albums, his phrasing is unbelievable, and that tone. I vote for Milt Jackson simply because he is the first vibraphonist I ever heard, when I was little (even saw him with the MJQ when I was 6!) and all the albums I have of his are wonderfully consistent. Note I mostly have the Pablo stuff, I really like "Montreux '77" a whole lot!
