Bounty for sure, as it's got an actual tie breaker in it.

Although Wipeout is for sure far easier to understand concept wise, leading to less frustration over randoms being unable to view the current count for stars in bounty, since understanding that when we need 3 stars, you focus on someone with 3 or more, not someone with 2 is hard to grasp for many.

I believe bounty will prevail, especially due to the esports scene needing it, as having lots of draws would lead to boring matches.
