MetaMask great, MEW aweful.
Would you mind explaining how MEW became awful for you? I use MEW and for me it is doing fine.
As I don't have a hardware wallet then I have to login in an insecure manner (ie via https with no 2FA but instead seed/private key).
Maybe things have changed, but until they support 2FA I wouldn't go near it. If I had a hardware wallet, it would obviously be fine.
Not worth the risk imo. Unfortunately a lot of new people to crypto aren't aware of the dangers.
