What's the best gauntlet? (as a whole)

Not to be that guy, but it's *7. 

But I do like Chaos the best solely because of Dark Drop and Kappaclysm (both of which were pretty fun).

Off-topic, my favorite gauntlet level overall (which people are probably gonna get really confused by) is Generation Retro from the Poison Gauntlet. It's really bad, but really charming.

I could have sworn it was Insane. Lmao woops.

Doom tbh. The only one in which all 5 levels were enjoyable, for me at least.
