Best current EL34 tubes


I need a matched quad and noticed that the svetlana. Electro-Harmonix, and JJ are all about the same price. Which are the best ones to buy for natural sound accuracy? Thanks for the help in advance.

I own a hybrid that right now has stock Chinese EL34s. I would like to upgrade. To that end, I found this post but I'd like to ask about the intent of Mrtennis 5-13-08 post. Not trying to be a provocateur but is that sarcasm? irony? The qualities listed seem desirable. Mrtennis, do you have a recommendation?
I've had some bad luck with the SED winged tubes over the last 18 months, and have 2 go in my Marantz 8, One took a resistor with it.
