Honestly, if all this time I always use MEW for my wallet, so far there have been no obstacles that could be detrimental. I have been using it for a long time, because I believe that MEW is one of the wallets that is safe to store my coins or if there are tokens that enter.
Don't you think that it's a little bit inconvenient to use MEW on mobile? You have to use browser on mobile to access to MEW cause MEW doesn't have mobile app while you can't set up 2FA for your MEW wallet that is the reason why there is no way that MEW is a good choice to use for ETH on mobile.
