KRZY-Takes: Your favorite extra game mode?

KRZYBooP: Howdy Boom Jockeys! Over the years there have been game modes put in the game that some find horrendous, and some that most players enjoy.  I wasn't around when the beloved 8 bit Karl tank was here for April fools, but I hear great things and wish I was part of the fun.  Out of 10, what would you rate our game modes so far? The Game modes I am referring to are: 
 8-bit Karl! Soccer mode Frontline Homefront Rampage Chaffee Races Race mode 2.0 Steel Hunter Waffentrager Leviathan Dark Front Any others I am forgetting?
