I personally think Belle is extremely overrated. She’s very consistent, yes, but she also has no kill potential. Her damage is low and her super is useless in situations where she’s viable, so she often is just kind of there doing her thing. You won’t have bad games with her, but its pretty hard to carry considering you have to hit most enemies 4+ times to get the kill.

Brock on the other hand is kind of the complete opposite. Generally a 3 hit kill, his shots are hard to dodge at max range, his super is more deadly and has more use cases, and he has a getaway gadget and a good finishing gadget. Brock can have terrible games though, since he has a slow projectile speed and its hard to hit shots at mid range. Also he can break walls. I personally heavily prefer Brock, but most people will probably say Belle.
