All of them hold up pretty well when binging them, although I do fairly slow binges, maybe watching 3 - 4 episodes a day at most. There are episodes I dislike and I simply skip those when binging, which helps a lot. (For example DS9 is my favorite Trek but I really, really hate Vedik/Kai Wynn and skip the earlier episodes where she’s being an annoying bitch. I do watch the later episodes where she’s a lot more important, but I still hate her character so much. For TNG I skip all of season 1 and most of season 2.)

The scenes in the isolation chamber in underwear applying gel to each other were totally unnecessary and unpleasant to watch, especially nowadays. They have aged very poorly.
