300B tubes

I'm considering tube rolling on my Nagra 300p. It comes with 4 JJ 300bs, and I am curious about the Gold Lion re-issue 300B (had a great experience with their KT88s in the past). I am also considering the re-issued GE 300B and the Shuguang Treasure. Reliability and sound are both required in this price range. No troubles with the JJ - just curious to experiment.

I've read prior threads and searched the net. Thus far, very little on the Gold Lions, lots on the Shuguangs. Cheers and thanks.
