For Nostr I use the LightningTipBot from @calle.
I like the backup from Phoenix (12 word seed). So far, Phoenix is actually stable for me.
I haven't tested Muun yet. The fees at Muun should also be a little higher? Muun works stable?
I haven't tested Breez yet too.
I like non-custodial wallets. Still have to try a few things 😁
