Which are the best re-branded Shuguang C9's to get?

[Rex Rocker]

I've bought a bunch of Ruby 12AX7AC5 HG's over the past year and they sound nice and all, but they all seem to be noisier and more microphonic than the JJ's I was running before.

So what are your favorite re-branded Shuguangs? Penta? Ruby? Groove Tubes? Anyone else testing these well and selling them?
