My favorite of these is Paul Motian On Broadway, Vol. III , which adds Lee Konitz and Charlie Haden to Motian, Lovano, and Frisell. An excellent record that includes a great version of "Skylark."
I haven't heard any of these albums, except for odd'n'end MP3s I downloaded. I guess I'll have to put them on the "to-buy" list. I think I prefer the trio without a bassist from what I've heard so far, though.
