Agree very much Shedder, concerning Virgil's ability to move in and WAY out of time with amazing ease, which makes his phrasing very COOL!
And as NoBells said Virgil's rhythmic innovations are much deeper and more creative, there is just flat out a deeper compositional depth there. Something about Virg that is not mentioned much is his amazing improvisational ability, some of the absolute best I have seen and heard, just listen to Just Add Water(whether you dig the musical style or not) all improvisation! and nothing else. I still dig both of them Virg and Lang in a technical sense though.
