Which do you think is better, and why?

Gx. It feels so much faster and I prefer how the cars handle

GX was simply amazing a near perfect sequel of F-Zero X, perhaps F-zero NX will be a thing, good game to show the power of the system.

F-Zero GX. I could give multiple reasons, but I'm just going to say this one: it is very satisfying seeing Captain Falcon being angry at some almighty powerful gods because of insinuating they can beat him in a race. You can't find that in X.

Never played either. From what I've seen, GX. Maybe F-Zero NX will be a thing and top both.

GX by far. But I still hate the ridicules difficulty.

I honestly don't think there's anything about F-Zero X that's superior to GX...
GX might be my favorite GameCube game...

Actually havnt played either of those either.... Been along time since I played a F zero game.

GX gets my vote too.

It's a tough call though, both offer ridiculous intensity, tight controls, badass music, a fantastic sense of speed, and a blazing 60fps. In the end though, I have to give the edge to GX for feeling even faster and more intense than X. Both great games though.

Both are good but GX is just one of the greatest racing games ever. Awesome music,graphics,blazing fast gameplay,60 fps It just perfect and criminally underrated. Hope we get a new F-Zero sometime soon.
