Just try them, it's not a big investment as they all work with vanilla server. You will appreciate default Jellyfin client more :)

I'm on Moonfin right now. I tested a few of them. They all looked super good, but turned out they were all super buggy. Unusable, even. Moonfin is OK.

Yet still, I come back to Jellyfin all the time. It's missing some bells and whistles, but it works in a predictable way.
