I also use MEW. Very comfortable and reliable wallet in terms of protection.
Mew is well known ERC 20 tokens but for those who have the capacity to avail a hardware wallet, then upgrade and go for it.
You need to at least strengthen your security especially for those who have large amount of tokens but this is for everyone even you have a small amount of tokens. I'm saying that everyone should strengthen your security and buying your own hardware wallet will do.
