I have been using Muun wallet for my partial-custodian lightning wallet for a while now.
Its quite stable, user friendly and much better than phoenix.
I dont understand why people are complaining about it.

what does partial custodian mean?
I can have my buddy connect to my Phoenix lightning channel lol idk features like this I like.. I can run my own electrum server with my Phoenix
High on chain fees cause big fees for lightning transfers, sure to Muun using submarine swaps. Muun was silent for days while this was happening
Muun also uses a non standard recovery method, unlike most other wallets.
These are the main issues with Muun. I'm using Phoenix and it is great. Muun was fine too, but I got burned by some high fees. That won't happen with Phoenix, your funds remain in lightning channels until you decide to swap out to bitcoin.
