Unity is free now too.You get it all now. Not a limited version. And Unity uses C# and Unityscript. Unreal uses C++ which is powerful but way harder to learn and use. Or at least that's what I have read. I'm going to try to Unity and maybe C#. Unreal does make some really nice eye candy. If you are looking at it just as a render engine Unreal has the upper hand.
