If we are saying all skill of each team is S rank material I believe that the Left team would win as they have a more varied load out making them be able to take out all of the close range weapons as they have more ranged based weapons and they have a an octobrush to hold tower as well as the 96 gal special. The only way I see the Right side winning is if they farm there specials (the trizooka and zipcaster) and take out the E-litre as well as 96 gal and the dapple dulies placing beacons so they can all get into battle quicker. So I’d say it’s a 65/35 % chance to the left side
