MEW has a great track record of dealing well under pressure and hasn't been hacked as of yet - We can see there have been phishing attempts but in actual fact the domain has kept its cool over the years. Its a great way to hold alts if you don't trust exchanges not to be hacked or manipulated... (Binance lol). So I shall keep using their wallets until i see a reason not to.
You got a point there. All problems i can see with myetherwallet is due to user's fault about their keystorefile/json file gone and private key gone too but in their platform or their wallet system i haven't heard that they had problems. Myetherwallet is being used until today and i myself use it too for erc20 tokens that i would recieve in the bounty campaigns. As for now there's no problem about myetherwallet until now so don't be afraid using myetherwallet. Try joining bounty campaigns you'll even see there are lots of bounty hunters who submit their myetherwallet address to receive their ERC20 tokens after the bounty campaign is reach it's target.
