Favorite nos tube?

With the recent best of threads I decided to do one on tubes. I know there's alot of us out there so let's here from ya. Strangly I replaced my Amprex Bugle Boy 6dj8 for the Sovtek 6922 reflectors. The sovtek just seemed to sound a lot crisper and detailed to me. I have not tried any other nos tubes so your input will help me and others who will be tube rolling in the future.
