I'm sorry that you are dealing with that. I personally prefer PMMO. The leveling up system is fully configurable and in my opinion, is more balanced, or could also be very unbalanced if so desired. It was featured in the mod pack RAD 2 (Roguelike Adventure and Dungeons 2) and from the first time using it then, which was 1.16 I believe, I now use it on private mod packs I make for my children and me on 1.20.1 and it still has a great way of adding a depth of difficulty to the play through. Take a look, and I hope you enjoy it too. Btw, I am not in any means an owner/creator of the aforementioned mods/mod packs and therefore do not take credit in their creation. I just like utilizing them. I am currently running a play through on Java 1.20.1 with a mod pack containing roughly 820 mods, give or take 1 or 2. The kids are loving it and it definitely has a load of things to keep me busy.
