Gyro Ball or Iron Head for Ferrothorn in a White Nuzlocke?

Hello, I would just like to ask what would be the best option between Iron Head and Gyro Ball for my Ferrothorn. I am playing a Pokemon White Nuzlocke.

I have seen multiple people say that Gyro Ball is better for Ferro. However, when I test which is better in-game, Iron Head has dealt more damage every time, even after a Curse.

I would like to know why Gyro Ball is supposedly better as well as why I am getting more damage from Gyro Ball. Thanks in advance :)

This isn’t even a close call for in-game usage.

I’m almost positive that the overwhelming majority of people who advocate for Gyro Ball Ferrothorn are talking about its usage in competitive online battling, where most of the Pokemon that you face in the OverUsed tier are much, much faster due to having perfect IVs and EVs than the game. Also, in competitive battling, PP isn’t a huge issue because you don’t have to heal after every battle. Whereas in a playthrough of White, you’ll have to face multiple opponents before you can heal at a Pokecenter. This is even more challenging for a Nuzlocke where you can’t afford to let Ferrothorn faint, and your PP usage will affect the next battle as well.

It is only true in OU (where Ferrothorn is usually used) where the majority of opponents (fully evolved, offensively based Pokemon with max IVs, all at level 100) are much, much faster than the Pokemon you face in White. As for why the extra damage, then it’s because of how the base power of the move is calculated, and the Pokemon in game are usually much slower than the required threshold.
