You should look into Cashu Wallet, and Coinos. Cashu Wallet is the basis for Primal's wallet. If you're familiar with Primal's wallet, then you already know how to use Cashu. It's an ecash wallet that also supports Lightning, and it has NWC for full integration with Nostr. 

Coinos provides similar functionality; Lightning, Liquid, eCash. NWC and a customized LN address for full integration with Nostr. 

Both wallets are web-based, so they can be accessed from the desktop, anywhere you go. Between the two, Coinos is a bit more user friendly, but it's custodial, meaning Coinos actually holds your coins. Cashu, on the other hand, is a non-custodial wallet, meaning you hold the keys, and possession of your coins.

Both are stable and reliable, and if you're looking for something to primarily interact with Nostr (zaps), both are fully suited to the task. I wouldn't use either of them for storing large quantities of bitcoin. For that, I think you want something that's based on on-chain bitcoin. Something like Electrum, or Mycelium.
