Which final boss was tougher: SS, Nova or Mojo?

Now that the new contest is available and a lot of players have already fought Mojo (I’m not even on chapter 2 yet, lol), amongst the three last final bosses, which one was the toughest to defeat?

Surfer is difficult to finish due to lifecycle I wasn't familiar with.

Nova is quite easy, nothing going on.

Mojo is doable through heavy attacks, I only hate that he punishes you for repeating the fight

Mojo is really freakin annoying. I finally took Gulk into UC for some degeneration recovery, even though I never use him. I’m very glad to be done with the monthly and not have to face that guy again. That being said, I found that it helps a little bit to stay away from him when the gas is active. Unfortunately, this seems to be about 50% of the time, and the degeneration is nearly unavoidable. It doesn’t help that just a few stacks can wipe out a full health 4/55 very quickly.

I didn't play the Nova event because I was busy with exams, but SS I mistakenly soloed him with scarlet witch but this mojo seems to be full of almost unavoidable damage ( Yes that scarlet witch was a 4*) and I will try to solo mojo with a 4* quake)
