Your NOS tube favorites.

Just wondering what manufacturers and models of NOS (new old stock) vacuum tubes you guys/gals really like? I have some GE 12BH7A (not sure of the date) that sound very good. Also tried the Sylvania 12BH7A and Sylvania FAA 6SN7GTB and JAN 6SN7W GTA (various years from 1968 to 1979)

Which tubes have worked the best for you?
