For advanced teams, the top bots are the 180 mech and the revolver. The revolver stacks way better but the 180 mech can create large “cactus” stacks easily. The 180 mech is easier to build than the revolver, but in cases of finding which one is better, it depends on what you’re aiming for. For teamwork, a revolver will outperform the 180 mech because the 180 mech can create a maximum of 2 cactus stacks (212 pts with stand-off goal), while the revolver can stack up to 13 3-color stacks (216 with no matching goals). However, for skills, the 180 mech will likely do better, since it can create two cactus stacks on its own in around 60 seconds. So, think of it this way; 180 mech is better for skills, revolver is better for teamwork.
If you don’t know what a 180 mech or revolver is, I summarized it in another topic: Can someone summarize the popular mix and match designs? - #2 by 76782AHighVoltage
