Always thought Electrum was a popular choice and it actually is for many people.
So I think they'll resolve their issues, it's been around for so long.
Core seems to be the best way to go If you don't mind running a full node.
I do mind running a full node, I wanted to kill myself after realizing that I'd get nothing if I run a full node. lol. Electrum is a good choice, it is open source and if you have something to add to the code to make it better, you should do it. if any other wallet is better than Electrum, you should use it.
