Regular Yahoo! Mail or Yahoo! Mail Beta?

So what do you prefer? Regular Yahoo! Mail or Yahoo! Mail Beta?

I used to hate Yahoo! Mail Beta because it takes a lot of time to display the mail menus. It was during the time where we have no internet connection in our home so I go to the net at Internet Cafes. When we finally had an internet connection at home, I observed that loggin in at Yahoo! Mail Beta is already fast. And I appreciated the features you have in Yahoo! Mail Beta. You can send an instant message to your friends who are online, finding a message and deleting a message is much easier, opening a message is fast,etc.
