Once you get to the point that you are able to communicate effectively, there really isn't any "better than the rest". There's just players that communicate to you more or less than other players. And it's not even that carved in stone, what speaks to you deeply on one occasion may not on another and vice versa.
And then there are those players who seem to speak about truth and beauty every time they put their horn in their mouth (or whatever).
Just about every good rhythm section has "interaction", even ones playing straight ahead four on the floor. We'll come back to that; what Scotty and Paul had was the ability to really break the time up but maintain the groove/forward momentum of the music. There's a great line from SNOWCRASH - the ability to distill meaning from the vapor of nuance. And those guys could make you hear the structure without rigidly defining the structure, either harmonically or rhythmically. Defining meaning from nuance. And for a bassist who just heard himself in that space, the first one really there in that space and there so strongly, well it was really affecting to hear that. I'm sure that everybody has their story of either hearing them live or hearing those Vanguard records for the first time and how that just opened a door on a new world. That's why they are "important" historically and musically. Personally it's inspiring to hear somebody with that strong a voice following their conviction and intent into such a beautiful space.
But like I said, all GOOD musicians have "interaction". Just like there isn't any "better", once you get to a certain point it's not "play in time and play lines of similar standard", what you are playing is a "mixture" of your internal conception of the tune AND how you are hearing the "mixture" of the other players. Your "melody" and the drummer's "melody" and the pianist's "melody" and the tenor player's "melody" etc. all have to be there because of what you are HEARING (both internally and externally)not because of what dots are on a page or what symbols are on a page or what changes you learned from the last guitar player you worked with. What are you hearing NOW?
If you think about playing jazz as a conversation, you will always find people who bring more to the conversation - deeper insight, more beautiful language, the ability to cut complex ideas to their essence, the ability to speak in such a way that you not only know what they feel but that you feel some aspect of it yourself and still acknowledge the weight and beauty of the language in which they express themselves.
But as long as you can express yourself, the ideas and thoughts and feelings that you have, in clear and precise language that expresses those things with as much specificity and feeling as you can, you get to take part in the conversation too.
