I stop using electrum when it became a hot issue before where the hackers can crack the code and can hacked funds from the users.
Electrum was vulnerable sometime ago before the 3.3.4, hackers were able to send fake update notification & if someone fall into that trap, they will lose their BTC. I guess it's not much fault from Electrum side, it's your fault that you couldn't use the software perfectly. I guess Electrum is one of the best wallet.
I just wanted to include Coinomi too.
I would include coinomi as well if it was bitcoin only wallet. As far as I know it's a multicrypto wallet.
