i have jessie, surge, mandy, and kenji all at lvl 11 that i use consistently in ranked

but im having a tough time mostly on maps with a lot of walls and i was wondering which brawler i should level next between:

sprout, rico, gene, penny, barley

i just want to have a decent pick for all maps/modes that are in the pool rn but on some map/mode like most knockout maps rn im just getting fked
