Been uhming and aahing about jumping into modded #BeatSaber for a while now.
Mostly I'm not good enough yet to be able to play most of the modded maps (I'm not yet able to do Expert+ in base game and I can only Full Combo the easiest Experts). Other issues around losing the ability to play multiplayer with my friends were assuaged by the existence of a mod that lets you swap between versions.
To test the waters I was mucking about with BeatSage, which takes a music track and automatically generates a map for it that can be dropped into the Custom Tracks folder without modding. The maps it makes are... an experience. They look like the BeatSaber equivalent of early AI art. You can see what it's trying to create if you tilt your head and squint a bit, but up close it's jank. Notes INSIDE walls? Oh well, at least I can dance* to music that's not in the base game or Monstercat DLCs.
*(in as much as my foot allows, which is improving albeit glacially.)
