The best thing about this email provider, it's very easy to use for both personal as well business purposes with its simple UI interface which makes your work easier in managing emails of multiple accounts at once time without any hassle or errors! I have not found anything that i dislike so far but if you are looking out something new then go ahead otherwise there isn't much difference between other providers like Gmail etc., So definitely try them all before finalizing one!! It helps me manage my mails from different clients (business & Personal) easily using just 1 account id rather than having 2 separate ones along side eachothers.
