Ultra sun makes for a much better nuzlocke experience
I would go for Ultra Sun, but that's just a personal preference.
Gen7 does have it's flaws and the start of the game is quite slow, but overall i really like the alola region and some of the things it introduced.
Ultra sun because the ultra games are generally one of the most challenging games in the main series
Ultra Sun is a very fun Nuzlocke. Make absolutely sure you prepare for Necrozma
Sword. Definitely Sword.
Play US and then Sword + DLC after. You can get most of the USUM legendaries/ultra beasts in Crown Tundra and IMO Sword with the DLC's is the more complete package. It's a case of saving the best for last. Some will disagree but that's fine.
