I have not focused on that site properly. However, I have heard that getting the project on freelancer is much more difficult as compared to others. But I am currently testing these sites and as you said maybe it would be an good site too. However, my favorite would always be Fiverr because it is the only site where the first project can be obtained easily.It depends, I like freelancer because they have millions of projects on which you can apply and also without any limits. You can easily earn bid credits there.
Many of my friends have received the first project on Fiverr within an hour only. This is a way to fast for a freelancer and good for newbie's too. That's why the first preferable site is always Fiverr.
