My favorite lightning wallet for Nostr is definitely @OpenSecret, simply for the "Nostr Wallet Connect" feature. Pro-Tip is to browse with Mutiny and Amethyst in split screen so you can get that one-tap-zap experience, straight from self-custody.
Fun fact: I'm still rolling with the same 200k lightning channel that I opened on the day I first tested the app at the Nashville Lightning summit. This channel will probably serve my zapping addictions til the day I die, unless @ZEUS implements NWC
