Iki Island is a somewhat meaty expansion to the original game, I think if someone enjoyed Ghost of Tsushima, they're going to like that one as well. The story feels more personal, and the setting while not that different, has some cool places to visit. Probably the main strength of the expansion is the fact that with the added activities, wildlife and enemies, there seems to be a lot more variety in exploration, though the gameplay loop remains the same. Overall, it's a short, worthwhile experience.
