I like the Telefunken's, although they are getting harder to find, and pretty spendy for matched pairs. I think the Siemens comes pretty close, based largely on the type of music you listen to. Brent Jesse is an excellent tube guy. Tube Depot just had the Siemens on sale for $149. I have not dealt with them before, but that's a decent price for a high quality NOS 6922 these days.
I am glad I bought 2 extra Telefunken's 2 extra Siemens when I had the chance a couple of years ago. They just keep getting more expensive.
