In the head to head selections that @Sumezlaid out, both games are quality choices for the homebrew and for the licensed game. There are some homebrews in there that are still in development, but the ones that I have played both the homebrew and licensed game, in many of the cases, I'd rather play the homebrew. I am referring to the "total" experience.
That is my opinion and you may disagree. However, even if you disagree and have played the homebrew shown, I would have a hard time seeing that the homebrew is way off in "total" experience comparatively. I can agree that I would like to see more homebrews at the caliber though. I do enjoy a wide range of homebrews though, from tech demos, minigames, competition gamers, and to the ones that sumez mentioned.
