Honestly, breaking away from D&D has been amazing. We've learned so many cool new systems and honestly, it's been a lot of fun.
There's a lot of smaller systems out there that are amazing, don't just try pf2e!
Getting away from d20 systems after a long Pathfinder campaign with my group has been great. All kinds of systems out there making you roll d6s or d10s, spend hp to cast spells, and build characters collaboratively.
