Game Engine Research

So I made the mistake of bringing up the next blog task over dinner with a programming friend and my fiancé, also a gamer... They decided to provide me with their opinions of several game engines, in no particular order (spelling mistakes mostly on purpose);
Unreal is Awesome
Aurora teh suxxorz
Steam is slow
Infinity is dated (not quite so infinite?)
Unreal has funny hit boxes
Aurora 2 has a fail z axis of death
Unreal is Joey's B*tch
Quake is slow, badly put together, has lousy hit effects and is very very old
Doom was great at the fake 3D

Now to see if the internet can shed any light on these words of wisdom....
