Yeah. JJ and EH are generally great in guitar amps, but have no place in any of my head or power amps (for anything other than rectifiers). If I must go new production, I'm all about Tung-Sol and Genalex.
The 5670W is one of the better tubes GE produced; rugged, good sounding, long lasting, non-microphonic. The Russian 6Н3П-ДР and 6Н3П-ЕВ are nice, not as good as 5670W, but dang close. I completely skip NOS 6922/6Н23П whenever possible, I find the prices are generally stupid... and I don't like stupid prices when I've a habit of buying lots of 50-200 tubes. :)
