I'll list all the ones I can (in no particular order):
1. Slayers
2. Cutey Honey ('73, New, and F; not a big fan of Re)
3. Candy Candy
4. Devil Hunter Yohko
5. Sailor Moon (Classic, R, and S; SuperS and Stars aren't that good)
6. Panty & Stocking with Garterbelt
7. Lupin III (I need to rewatch this one)
8. Tokimeki Tonight
I've seen more than this, but these are the only ones that I was really into. If it's any consolation, Slayers is 104 episodes long, not including the OVAs and the movies; Cutey Honey '73, New, and F have 72 episodes combined; Candy Candy is 115 episodes long with three movies; and Sailor Moon is 200 episodes long with three movies as well along with some specials, so I've been busy. haha I'll fill up the rest of it with things I'm excited to see:
9. Devilman
10. Mahou no Mako-chan
11. Majokko Megu-chan
12. The Rose of Versailles
13. Hurricane Polymar
14. Hana no ko LunLun
