Primal is the easiest in most the US because it’s Nostr-powered and there’s no channel setup, but I make sure to remind them that it’s custodial and they will also need to use another wallet (usually Zeus) where they hold the keys.

For those who live in the People’s Republic of New York, I usually start with LightningTipBot and show them how to connect it to Zeus where they can then create a self-custodial wallet in the same app.
