Ok, I'll take it easy on you.
No one but you knows which three amps you're trying to compare. Naming manufacturers is not specific and technically, Pete's not a manufacturer. He has, at times, produced commercial products under at least two names (Wheatfield and Apex) and has also published numerous DIY designs. At least a couple use 6080 (or pin-similar) tubes on the output. Woo has made so many amps I couldn't begin to guess which you're talking about but I don't have schematics for any of them. I'm not going to give any thought to Darkvoice.\
Second point - if you want DIY advice that's fine. Asking us to compare commercial designs isn't a great start.
