Adult link, what impressed me the most when I first played zelda being a kid (oot) was that you were a boy who took a magical sword and grew older and stronger to become the hero of time, I miss the "growing up" concept of Zelda oot, it was in my opinion the most fascinating about zelda, to play the same character but differently, when you're a kid you can do certain things and when you're an adult you have other abilities but lose some. I also like being adult link in twilight princess and skyward sword but I dislike when it is just toon/young link. I find it makes it more childish when you get to play only as a kid (except for MM of course wich has pretty mature and dark themes)
