Haven’t seen anything in 140.0esr that would make me downgrade back to 128. That’s with 14 accounts (about half IMAP and half POP, (all IMAP IDLE), about 120,000 emails, about 300 folders, sub-folders and search folders, and about 200 filters.
In fact, feels much snappier. Like selecting with CTRL+A on large folders is immediate, on 128 it took about 2 seconds (all accounts set to maildir). Moving stuff around is much faster too. My userChrome.css still works as in 128. Sorting Folders works great too.
