I have all 3. Gmail is the best, lots of features. Hotmail isn't bad at all, really good against spam. Ymail is horrible with ads and spam. I hate it and will be killing my ymail account soon.
They each have their own little thing that different people like over the other. This is totally an opinion-based topic. I personally don't even care as long as I can add contacts and send/ receive email.
Hotmail or Gmail. Yahoo is so full of Spam. within days of signup and not even sending any emails or posting links anywhere I get tons of spam. Gmail seems to be the best at spam control.
Gmail is the best when it comes to spam protection. Yahoo and Hotmail seem to be the worst - yahoo mail and hotmail should be rename spam mail.
i use gmail for somethings and yahoo for others yahoo (the new version) is much slower when dealing with over 1000 emails
yahoo has all in one package , what i mostly like is that it saves the data while chatting , and can send offline messages. Gmail would have been great too in sending big files . hotmail case sensitive.
I like gmail the best because of the chat and it also has a lot of memory space and a nice spam filter
