I think they are pretty mediocre.  I keep reading stuff like this and buying them thinking I’m missing something.   I’ve owned the OG 6L6, the concentric 6L6 (twice), and the Stealth.  I agree with the “plastic” comments.   Also found a serious lack of punch…….just a flat SS type tone.  I greatly prefer the 5150/6505.
