I would recommend Electrum for the desktop and the mobile phone, Phoenix for Android phones, and Wallet of Satoshi for the very beginner to start learning with tiny amounts (50-100 sats), since it's a custodial wallet, to later learn about channels and move to one of the others (non custodial).

I would strongly recommend against using Muun, since it isn't a LN wallet, but it uses submarine swaps to do LN transactions, and therefore it makes on chain transactions for every LN transaction. And, the worse of all, is that they hide that, and in my opinion, lying about it is the worse.

It seems, though, that they have received so many criticisms about that model that they are making some changes to have actual LN transactions. Let's hope it's true and they are honest about it.

I didn't vote but on my experience the best is phoenix.

Everyone has their own use cases and needs, and not all LN wallets have a similar design.

For instance, when making the bond payment on RoboSats, Wallet of Satoshi handles that the best.

For general use, it depends what I am doing. When I am on my laptop, CoinOS (web) is what I prefer to use. I like CoinOS because I can copy/paste LN invoices and transact without even having to touch my mobile. But CoinOS doesn't (yet) permit me withdraw to a Lightning Address. But fortunately, their classic.coinos.io, the old front-end web access to my wallet, does support withdraw to a Lightning Address.

When I am demonstrating LN to someone, or perhaps actually using it for payments like at a retailer (a rare occurrence), I sometimes will use Blue Wallet, and other times use Wallet of Satoshi.

When doing transfers of any amounts of significance (e.g., receiving from an exchange, or buying a gift card on something like Bitrefill, or topping up my LN wallet for additional spending) I could see using something like Muun. But I wouldn't use it for the vast majority of my LN transactions, which are not economical if I were to try doing those an Muun.

There are a number of services that have trouble with Muun. For example:

Muun is fee siphoning attacking any sender to Muun wallet #110656 https://learn.robosats.com/docs/wallets/#muun-mobile

and

What do you mean? If you use Muun, you should notice if you pay high fees or not?
