Problematic poll. A number of these are remasters, including all the Zelda titles listed.
Personally, I would say the best remake Nintendo have made is Fire Emblem Echoes: Shadows of Valentia which, bizarrely, isn't even an option here! Followed by Samus Returns. Both turned archaic, black sheep into stylish contemporary games. I'd also say that Heart Gold is my third favourite Nintendo remake.
Ocarina 3D and Majora's Mask 3D are my favourite remasters.
