blitzball v.s Quidditch

which one would you rather exsist?
for those of you who do not know,
blitzball(final fantasy 10) is a sport where players can play in a round aquatic sphere, where you play with one ball. In order to play this sport, you need to know how to swim, and fast! it's pretty similar to water polo, except is under water this time, and alot more fun as well as extreme.

or...

Quidditch (harry potter franchise) is a sport where you use broom sticks to fly on. a team usually consists of a two beaters, whose jobs are to attack the bludger(a flying ball which can kill you). three chasers, whose jobs are to throw the quaffel into the goal. a keeper, whos job is to secure the goal. and last but not least, the seeker who is in charge of capturing the golden snitch. the sport takes place in the air, and can last for days. to play this sport, you need to find perfect balance on a broom, so fat people...sorry. a little bit like polo, except this time no animals to ride on!

both sports seem amazing to me, but i prefer blitzball, only due to the fact that i find it a little more challenging.
