I like the GMAIL interface, I run it all day long(literally). I've used other webmail like the new and improved AOL and Yahoo, but it's too feature rich for me,it takes up too much processing power of my 1.4ghz aand 512mb ram puter and I am already used to using GMAIL. At work I am forced to use outlook, but would much rather use thunderbird.
