>>38392666DPT only ends up mattering for the purpose of convenience if you can control how often you take damage from attacks.
Ex: If you were fighting an identical Pokemon that only used Wing Attack and you used Fly, you would deal more DPT than they would, because Wing Attack would only land every other turn.
The only advantage would be that battles would be shorter if Wing Attack would've also killed, or you could kill the opponent before they set up hazards or buffs/debuffs.
