Black sable tube how good?

I’ve seen these tubes costing double of what some favorable Tubes are costing.
I was looking at the 6922 type.

Are they just cherry picked , matched triodes with top specs? Are they cryo? I think I would just trust a guy like Jim McShane or Brent Jesse if i'm going to spend 100 bucks on a 12ax7 or 6922 .....
