I have Gmail. It's search feature has me spoiled. I hate using anything else because I can't search. It's a pain at work because I've got thousands of emails, but I put them in archived folders to sort of help the lack of searching. My school (don't really use that email address anymore since I graduated) as well as webmail at work migrated to the new Outlook exchange server, and it sucks. If you're in an email and delete it, it opens the next message instead of going back to the inbox.
I also have a Verzion email account, which I never use, but it's pretty clunky like most others. I had hotmail until I stopped using the account because it kept getting clogged with spam. Of all the ones I've used, I think Gmail has the best spam filter. Hotmail was years ago and was terrible. But I don't use the others enough to really guage. Well, except for my school account, which has a terrible spam filter.
