Not an expert, but researched a bunch before buying one, and I think those are just a smaller run from like the late 80s. Probably a red knob era circuit.
What I really want to know, when the Jose is switched off, how good of a 100w Plexi is it?
I used to own a Friedman modded Plexi that he made sound just like his '68 (and now the Plex) and I completely regret selling it since all the other Plexi's I've bought just couldn't measure up.
I've got a Hellion and a Wizard MCII, both are keepers. I don't have an Alta but that one sounds most true to a Marshall from the clips I've heard.
The Wizard is very clearly a modified Jubilee, so it's a question of how close to a Plexi you really want (given those influences you mentioned)...
East Bay Ray from Dead Kennedy's because that dude managed to mix surf music with punk music and I think that sounds sick. I basically aspire to something similar but more with spaghetti western and hardcore.
Jimmy & Angus because that's what I hear in my brain when someone says rock'n'roll...
Sounds good, would never ever come close to buying one anywhere near that price though.
Like my ceiling for those tones/features would probably be like $2k new.

Looking at an E series by me at the moment as well. TLDR of them from what I can find is the wood working is great but the electronics are garbage (hence someone dropping some Laces into yours).
Chatted with a local tech and his recommendation...
Ground lifts are tricky...they're not always well places in your signal chain and are technically unsafe for amps.
Passives boxes like the Lehle P-ISO solve those problems though.
Invest in a noise gate that does the 4CM, it may introduce a ground loop (solvable) but it will make your rig usable if you've got a lot of feedback going on.
I'm in a similar boat (high gain, volume cranked, sit in front of my cabs) and make it work with a Fortin Zuul+ (silence the noise...
I'm so surprised since I hate rectos and own(ed) a ton of Marshall based amps, but I think I like the Rectos better from him (at least based on the handful of clips).
