Idk I like versing Chucky but also I know how to play against him. Most survivors are stupid and can’t learn the counterplay of running in a huge circle when he slice and dices. And I’d take Chucky any day over killers like Nurse, Hillbilly, and Blight. At least Chucky has to actually play the game.
As a general rule of thumb yes I'd take Skull Merchant over a good Chucky most days. The only advantage really is Chucky is 4.4 and his stealth is not truly stealthy (thank you bhvr) but other than that Chucky is far more irritating to vs than Mama Drone.
And honestly I feel like both of them are less irritating to face than killers like Hillbilly who don’t get any punishment at all for misusing their power. Like at least if Chucky misses slice and dice he has 2.7 second cool down and it’s not available to him for 10 seconds. If Billy misses an insta down chainsaw hit he can do it again like 2 seconds later.
