Which is your fav Beethoven String Qt version?

I have the complete Quartetto Italiano set on CD, and one version of the Early Quartets Op18, Middle and Late Quartets (Vegh).

Not fully satisfied with the ones I had, I went looking to gather another version which would do justice to the complete cycle and I think I've found it with the Alan Berg version. Somehow this version seems to be paced "correctly" (I didn't fall asleep), and is well recorded on EMI. The music flows continuously and speaks to me. Highly recommended.
