I have played this and a few others extensively and I have to say I much prefer armagetronad.

It really boils down to two reasons, first I can run a native resolution and second the camera work is much easier to handle. Although I do prefer gltrons' artwork and especially the music making a more submersive experience.
If you play multiplayer you really do notice the difference. I like to use the arrow keys to quick look in a direction and just z and x for movement.
