MEW is fine so why would I stop using it?
I never used mycrypto and even there are some problems that has been showed with MEW, its still the most convenient wallet so far that I can use if ever I want to.
I think MEW is the best and safest wallet, with various security features and features so I made MEW as the main wallet to store ethereum and dozens of tokens that I have.
I'll not end up with that statement that MEW is the best and safest wallet.
If that's the story, safest and the best wallet for me still an hardware wallet and that would be Ledger Nano S, IMO. I'll choose to say that because I have that wallet and never had issues nor problems by the time that I'm using it and with those updates and support, its amazing.
