I would add Russian Yandex Mail into the list. Google Mail is the best but they no longer allow own domain support for free but the Russian Yandex does it with unlimited mailboxes.

gmail is the best! once you have it, it's like the whole world is at your fingertips!
very good mail provider...
speed...
compatibility on mobile phone...
easy to access...
google offers really an integrated service. easy to use even for a beginner. uncomplicated. additional benefits are there. ecent changes have made it more attractive.i think gmail is the best because gmail has built-in "google talk" and i can chat my friends all around the world.
and you can change your theme in gmail. google also has 15gb of storage, support for 25mb attachments, support for multiple external mail protocols (imap, pop pop+tls, microsoft exchange) gmail also works on windows live! i use my gmail for xbox live and other various things and its just that one address. vote for gmail!

Same,I am using Gmail mainly because when I was making Google account I needed mail with other address than my first.

Ofcourse gmail. But i like photonmail too. Most secure and encrypted mail service. Awesome free options too. I urge you to check it.

I've used both Gmail and Outlook (previously known as hotmail), I myself prefer Outlook, because we can create e-mail aliases unlike Gmail. Also I use my Live account so much unlike my Google account which is barely used.

You can create alias on Gmail too, but it is a little more difficult than it would be on hotmail

Please tell me how can I create alias on Gmail? 
Using (.) dots? Or registering multiple addresses one by one?
