I was thinking which is better, UDK or Unity3D. The graphics of UDK is really awesome and better than Unity. So I was also thinking about the programming language they use but I'm using mac so I also don't know what UDK is using. Which is better Unity or UDK? Please explain. (Maybe the graphics?Collision?)

Unfortunately, it is not possible to write an objective answer about which engine is better, as there are a myriad of factors that come into play when selecting an engine to develop atop. Unity has a free version and UDK is free for non-commercial use, so I would recommend grabbing copies of both and trying them out for yourself. After you spend some time in both, you can determine which engine best fits your needs.
