Static and Flame Body at least stay consistent and stick to Paralysis and Burn, respectively, so you know what you're getting yourself into when clicking a contact move vs them. Dire Claw not only has a much higher chance to proc something when factoring in the move's 50% effect chance on top of the 30% Poison Touch chance, but it's a dice roll whether the target is getting poisoned, paralyzed, or slept.
I agree with Return to Zero. If Static and Flame Body are gonna get included with Dire / Quick Claw, gotta go against other mechanics, too. Effect Spore, Serene Grace, Poison Point, and the plethora of other moves that have a chance to do something like Lava Plume, Thunder, etc. I'd rather discuss Dire Claw since it can choose 3 status conditions that the opponent has minimal counter-play against. It can be bringing in a Steel-type that could be hit with a Fighting-type move (unless you're Gholdengo), bringing in someone with Covert Cloak, or bringing in the bussin' Shield Dust mons.
