the PSVANE ART-S series are pretty tough to beat sonically.
If you are looking for more midrange warmth, the RCA black plates are a great choice.
It's really circuit dependent how a tube will sound. While asking for others' advice is a good starting point, this is something that you will have to experiment with first hand. Buy a bunch of tubes and switch them in and out. You may have a strong preference, or you may not. Sell the ones you don't use. Brent Jessee is my go to tube guy.
