Terrible choice. Pick something that boosts your overall ability to learn. That would encompass other things like magic or use of technology AND all forms of fighting. Also, why would you pick martial arts you could learn in the world you are going to? Why not pick op martial arts like bangs or something from a fighting anime?
Objectively speaking, Saitama's "potential" is not a good "cheat" to have in any world, because you don't have his strength, just his strength potential and that really isn't a big deal since there are entities that simply don't can die from physical damage. It would have been better for him to ask for a potential like Saitama's, but for magic that is more comprehensive and not limited to just the physical. People tend to think that Saitama is the strongest character, but no, he may be very strong physically, but that's it, he can't even fly (It would have been better for the mc to ask to become a Kryptonian or something, even if he had to "train" to gradually unlock potential)
