Yes , I am still using My Ether Wallet (MEW) . IS there any problem so please let me know . I think it is safe to use MEW if used properly and not giving your private key to anyone will be the best choice .
That sounds easy but you don't know when will you get attacked by the hacker and if you are accidentally submitting your private key to a phishing site that'd be a serious problem.
You can use web wallet all you want but just be sure to keep checking on your security and use 2fa or hardware wallet if possible.
