Link from Majora's Mask and Link from Breath of the Wild.
Majora's Mask Link has experience as an adult warrior, to the point that even though he's physically a child again, he can ride on Epona and use a bow with no issues. It also allows him to take advantage of his opponents who would underestimate him (while it's non-canon material, the manga even points this out in the opening chapter.) Not to mention he's got a collection of masks behind his belt.
Breath of the Wild Link is rather interesting in personality (what little of it we hear about), as he's just as nervous about his destiny as Zelda is, to the point that he puts on a stoic act to silently bear it. It speaks volumes to his commitment that despite his amnesia, he still takes on the task of rescuing what is left of Hyrule before Ganon can completely destroy it. Also, he loves food.
