What is your favorite web-based email service and why?

My favorite is Inbox (http://my.inbox.com/) but I am currently using Gmail (http://gmail.google.com/). I also like Juno (http://webmail.juno.com/)/Netzero (http://webmail.netzero.net/) and Lycos (http://lycosmail.lycos.com/). Fastmail (http://www.ftml.net/mail/?STKI=1146658) is great too. The new MSN (http://www.live.com/) beta is okay.

I say Yahoo rocks.

I have been using them for year, no spam.

I have used Hotmail as well, way too much spam there.

I'm going with GMail. Their mail app is just far superior to any of the others in my mind.
