Is modding worth it (or even allowed on steam)

Idk if I can post this here because a mod sub I found is mostly for bugs etc.

Hey so I bought the game on release but haven't really gotten into it because I was waiting to paky with a friend. We've completed most of the characters in the episode mode and I'm currently exploring the rest of the game's content. I was wondering whether you guys use mods, if they are allowed on steam or you risk getting banned and whether or not you consider some mods essential. I don't care for mods that add characters like ego Vegeta or whatever. I remember seeing at launch mods like the one where it adds sparks on the aura of ssj3, or a Goku early move where he stands on the head of the enemy like he did on Nappa. You know mods like these is what I'm wondering about.
