Pros
MEW has the greatest advantage of being secure when you can connect directly to Ethereum's blockchain without going through any intermediate gateway. Just turn off that tab, all connections terminate, no one can interfere with your account. MEW can also incorporate hard wallets like Trezor and Ledger Nano S to enhance wallet security.
Cons
However, MEW has the disadvantage that every login has to do many operations, including accessing MEW's site, selecting files or having to copy Private Key. These small steps are at risk and can be hacked if the computer is infected with a virus.
