I’ll stick with Yahoo mail. Yahoo is the Cadillac of email services.
I have to say gmail does have some really nice features. Like if you get into a back and forth email session you have a reply tree that shows all of your emails for that particular starting email, plus it has a cleaner and much more intuitive setup than yahoo.
Now to be fair I really like the new m.yahoo.com they have been beta testing on occasion, very nice setup and you can consolidate some of your email services(even gmail) into one mailbox. Plus the preview shows three times as many emails as the current preview does.
