Fun vs Balance

I'm making this thread just to see which is more important to the community.

We're talking in general here, not specific examples.

So if there was a champion called "Killatron the overpowered" who's ult just executed the whole enemy team no matter what, this thread question would not include "is Killatron fun to play" vs "is Killatron a balanced champion"

Just in general, but specific to this game. Which is the more important focus to you. Would you be happier with this game being a lot less fun but more balanced, or a lot more fun but less balanced.

Before you answer there's a concept I think is important to consider. Fun to play as vs fun to play against.

Things being the former and not the latter is pretty much rule of thumb I think. Stealth is fun to use, but not fun to get surprised by. It's fun to use executions, but not fun to get executed. Fun to steal the jungle objectives, not fun to have them stolen. Before you evaluate something's fun factor, you have to consider both ends. Both ends matter, but I think the former is more important. Because if you put to much focus on avoiding things that aren't fun to play against, you'll run out of things that are fun to play as.
