Nevertheless we can sum it up and say that both engines are amazing, render dozens of highly detailed and animated characters with shaders, big levels, vehicles, indoors, particles, network, AI and highly detailled weapons in view.

I personaly like the artworks of ETQW more than those from UT. I could show what I mean with images, textures, characters, vehicles, but since I only know the demo of UT (which is said to have medium textures only) I will just leave it like it is.

You can enjoy your meal, but you should enjoy your game
Whatever game you choose, it is made to have fun and nobody can convince another person of his own fun-preference.
