This is how I personally divide up each season of the original anime into sub-arcs, and my own names for them. Legit, these are just the names I always associate with each run of episodes, there are probably better fitting titles out there though.
Sailor Moon Classic
[001-013] Classic 01-13: Jadeite Arc
[014-024] Classic 14-24: Nephrite Arc
[025-035] Classic 25-35: Rainbow Crystals Arc
[036-046] Classic 36-46: Dark Endymion Arc
Sailor Moon R
[047-059] R 01-13: Hell Tree Arc
[060-074] R 14-28: Rubeus Arc
[075-081] R 29-35: Esmeraude Arc
[082-089] R 36-43: Wiseman Arc
Sailor Moon S
[090-102] S 01-13: Kaolinite Arc
[103-111] S 14-22: Eudial Arc
[112-119] S 23-30: Mimete Arc
[120-127] S 31-38: Mugen Academy Arc
Sailor Moon SuperS
So, I honestly struggle to view this seasons as having four arcs like every other season. It actually divides quite neatly in two halves. Nevertheless I sort of have a mid-way point for each sub arc.
[128-138] SuperS 01-11: Amazon’s Trio Arc Part A
[139-149] SuperS 12-22 : Amazon’s Trio Arc Part B
[150-158] SuperS 23-31: Amazoness Quartet Arc Part A
[159-166] SuperS 32-39 : Amazoness Quartet Arc Part B
Okay so you know how Saturn never really got a proper transformation sequence in the 90s anime, besides a short clip in a Sega Saturn (ha) game? Well I have some questions about that, because if you watch that "transformation" closely, you'll notice an odd cut at the beginning.
Did you see it? Here's a frame-by-frame of it:
We start with a close up of the top of her head, which based on the sheer amount of black seems to be the back of her head, then abruptly to a close shot of her tiara, which in two frames fades into a shot of her whole face.
It definitely seems like something was cut here, and based on the fact that every other transformation sequence in the game is cut down from a longer version, I don't think it's too out of the realm of possibility that Saturn's is the same, that they animated a transformation sequence for her and then for one reason or another never ended up using it in the show.
Or maybe it's just an error and I'm overthinking things, but still, I feel like the possibility is there.

Sailor Stars is exceptionally awesome and in the conversation for the actual best season of the show. The main reason it isn’t is because most english language fans discovered it later in life thus it couldn’t compete with their nostalgia for the earlier seasons.
SuperS is not as bad as the fandom makes it out to be. There are some standout episodes in the first half and the second half is a huge improvement, ending with a solid finale.
Sailor Moon S is good but overrated and by no means clearly the best season of the show. It has major strengths that for sure put it in the conversation for best season, but the Outer’s attitude and the central ideological conflict of the season have major flaws that get overlooked mostly because the novelty/cool factor the Outers bring to season.
Sailor Moon R is good and has never deserved the negativity it has received. The Hell Tree arc is not filler and lets us see Usagi and Mamoru fall in love arguably more organically than in the prior season. The Spectre Sisters are the greatest foils the Inner Senshi ever had in the show. Chibi-Usa’s not as much of a brat as people make her out to be and in fact she and Usagi have a proper arc to their relationship going from out-and-out antagonistic to embracing one another as mother and daughter. The break up was a highly effective emotional GUT punch and the consequent arc played into the central theme of the season, which was Usagi and Mamoru’s future together.
Sailor Moon Classic...has 100% the best finale of any season. Tightly written, equal parts inspiring and tragic, with a laser focus upon Usagi herself whilst giving every major character a chance to shine, even Queen Beryl and Luna. By contrast every other finale divides attention between Usagi and other characters and/or sidelines the Inners, the Outers, etc.
