I'll stick up for the good ole 6DJ8: Amperex orange label from the 80s. Great tube that bettered several 6922s in my VK-3i. It has excellent dynamics and transparency without sounding shrill or brittle. There is more performance overlap between the different types than some would lead you to believe, in my experience anyway. The right choice depends more on your system and tastes than anything else.
