https://iris.to/ looks nice to me and logging via nos2x browser plugin, not sharing private key, just signing a message for authentication is acceptably secure

https://iris.to/ is also nice

and of course one can have multiple different keys for just browsing

I still use Gossip and keeping my main Nostr account keys local and away from browser or mobile apps, security first, live free
