For me it's Mashle, the Apothecary Diaries and Frieren as top Peaks.
Ragna Crimson is the hypest battle anime airing right now. The fights are way more peak than anything Solo Leveling will have until the Ants arc.
Classroom of the Elite Season 3 is my guilty pleasure. I just love the bullshit in this one.
I haven’t started Winter 2024 yet, cuz I like to wait. But yeah, anime still airing from Fall 2023, in order of preference and recommendation - Frieren (literally perfect), Apothecary Diaries (would be top if Frieren didn’t exist), Shangri-La Frontier (if SAO was actually good), Undead Unluck (JJK, CSM tier), Firefighter Daigo (realistic firefighter anime) Ragna Crimson (surprisingly not trash - won’t ever rewatch, but will finish the season).
