What do you use Nitrogen VS normal air in tires as a fill

All my replaced tire services have been done by Costco so far, so it is nitrogen filled. My 2019 MDX is still on original shoes, so it is whatever from manufacture. But I did top with nitrogen air from Costco few times over the winters as needs.
