There were 2.5 major ones for me:

1. Higher upload limit for game clips/highlights. OBS didn’t handle transcoding the stream down to a lower resolution without hitting the GPU hard enough to make the game stuttery
2. Higher stream resolution/fps. This mattered less to me as the homies aged and played games less frequently
3. Use the obnoxious custom emoji reactions between servers. I could upload some real egregious shit on a test server and use it in the homie server
