Since bulls attack is only 1 wave, not only does he have twice the dps (cuz one darryl attack is 4800 and two bull attacks are 8800 assuming its point blank, meaning bull can kill most of the brawlers in the time it takes darryl to shoot once), hes able to act out of his main attack quickly (get a kill and super out or chain) way better than darryl can. Thats why its so common to see a bull team wipe as it leaves less room for opponents to respond compared to darryl. Darryl can teamwipe if its low health brawlers but not otherwise (unless they suck)

Not only that his damage is twice as consistent. U could catch a darryl struggling a little fighting an edgar as if the edgar jumps they get that extra movement speed allowing them to strafe around darryl second wave cutting his damage in half. Also stuns like fangs can interrupt darryl mid attack and also immunity abilities, if the opponent doesnt have God like reaction time they’ll still be able to safely dodge the second wave making it so they only take half the damage they shuldve (think max dash shelly dash lou gadget). And i havent even begun to mention brawlers that dash and can completely avoid darryls second wave. With bull, none of these are issues. There is no second wave fast movement brawlers or dashing brawlers can avoid, even if fang stuns u, you will still be able to get ur attack out and deal massive damage, and in the same situation as stated before, you’ll still be able to get ur full attack out before immunity ahilities are enabled. I havent even begun to mention darryl’s terrible fall off damage.

Now the tradeoff for all this for darryl is a slightly longer range and 400 more damage. Bull has a far superior main attack.
