As I get older, rewatching entire seasons requires an emotional engagement I simply don't have with DIS.
I would certainly rewatch TOS and TNG in it's entirety (if I had the time...). I love those shows, and they get better with every rewatch.
The only "season arcs" that I find rewatchable are ENT's 3rd and 4th season - those are excellent story arcs where every single episode gets better as part of the overall arc/theme - even if the single stand-out episodes arent that impressive, the arc(s) as a whole really benefit immensely from the connected storyline.
For VOY (I LOVE VOY! Go fight me

) and DS9 - I find they have WAY too many boring filler episodes to re-watch completely: On VOY usually a bland conflict, on DS9 episodes where barely enough happens to qualify as a b-plot in any other series (Someone trades a baseball card, servers want to form a union), stretched out over 45 mijnutes. That being said - both these series have singular episodes, that belong up to the very best Star Trek has ever put on screen, and rival the movies. Something like "Scorpion I&II", "Duet", "Flesh & Blood", "Inter Arma Silent Leges" are episodes I could rewatch endlessly. Especially VOY has quite a lot of episodes that are
simply perfect to rewatch, even if they aren't "perfect". Episodes centered around Cpt. Proton, the Hirogen, or interesting stuff like the space race with the Delta Flyer or the doctor (like "Prometheus") are just a blast to watch, and often times more entertaining than any of the "great" episodes from other series.
As far as DIS is concerned - I simpy haven't been invested in any of the two season arcs so far, so re-watching them makes no sense. And the single episodes usually are not as unique to be worth the time (The time-loop episode was fun, but I'm much more likely to rewatch TNG's "Deja vu", which is essentially the same concept, just better).
There is one big exception though: "If memory serves". That episode is amazing on it's own. It's part of the larger arc, but it also works perfectly as a narrative on it's own: From the original mystery, to the great tactical poker-game between Pike & Leland in the end. And it has so many stand-out elements, from the Pike-Vina scene, to the black-hole illusion, to everything on Talos, to the final ship-to-ship confrontation, it's just a blast to (re-)watch.
Other single DIS episodes I would re-watch are "Lethe", for it's excellent character study of Sarek, and "The sound of Thunder", for being a perfectly classic Trek allegory episode with
amazing alien creature design.
Overall though, I think DIS really suffers, not because it's arc-based (that's even a plus - see ENT), but simply from
having only weak arcs so far, which drastically reduces the overall rewatchability of the series in it's entirety, and leaving only few self-contained stand-out episodes inbetween.
