If you know what you are doing, BOTH.
if you don't know what you are doing, NEITHER.

Damnn, I really love this reply.
But unreal has better graphics.

When it comes to Next gen graphics i haven't seen any engine that beats the Unreal engine, i've read that the next Unity release will be focusing on that aspect, Unity is very easy to use that's why its more popular and again the Unreal engine was built to make FPS games, but with hacks you can make any kind of game with it.

but for a platformer game, i think Unity will suffice.

Hope this helps 8-)

All these game devs, none of you want to make your engine

who told you, they're alot of Nigerian made game engines, some of the devs just dont take it serious, they build it as a fun project and leave it lying on their computer.
