It's just an upgraded and more nicer version of your creator studio now...

I prefer it but I'm still using the old one as there's still a lot of bugs that need to be worked out.
Just try it. It's not a permanent decision. You can switch back straight away when your bored of it. Which won't take long as most of the features are not yet enabled when I last looked at it. It appears when they have finished it will be a bit better presented and laid out better than the present creator studio.
