What is the biggest advantage of yahoomail over gmail?

weel i have been using gmail for last 3 or 4 years and i havent faced any problems yet and so i thing its simply the best...... its storing capacity and services it provides us is just too good and I dont think that yahoomail can compare gmail...!!!!!! the thing which you said would might be right but just because of one good service you cant compare yahoomail with gmail.....

I am using gmails for two and the half years.Thanks for this information.I will try to create an account in yahoo mail.
