Mijknarf, Distortion has taught me there is no "best" tube. It's all system dependant. For my system, it is black plates or nothing.
Unless... How in the world did you come by Sylvania Grey plate gold pin tubes? That's a good find. You really can't expect more with the black plate. Congratulations.
The Electro Harmonics 12AX7 tubes have a great midrange, but are rolled off at the top.
