Everybody's ears are different but Exo and I have literally compared like 5 rectos back to back, including two of the reissues. And except for the Triples, they all sounded close enough to where you wouldn't know which one you were playing if your eyes were closed. The reissue uses all of the same exact parts, including transformers, as the '90s rectos. There is literally zero difference except series loop and no LDRs (a good thing), and it has brand new components instead of 30-year-old parts that have had time to drift.
But none were Tremoverbs. I've not played one of those, so if that's your reference point, then who knows. And we didn't really focus on the orange channel. We stayed in red/modern on all the amps.
Will compare the reissue to a Rev F soon as well.
Here's a great video of a bunch of different versions too. Are there subtle differences? Yeah. But to your point, in a mix you aren't going to hear them:
