My (10 year old) brother has struggled to get into any Zelda except for Ocarina of Time 3D, which he not only got into but has beat multiple times. I think the primary reason for this though is that it's on a portable console. He doesn't have the attention span to sit in front of a TV for enough time to beat a Zelda game I don't think. Therefore I guess next up is to let him play Majora's Mask 3D!
My personal rankings for the 3D games are:
1) Skyward Sword
2) Twilight Princess
3) Ocarina of Time
4) Majora's Mask
5) Wind Waker
