Altmer would have to be the most magically talented since they are the closest thing you can find resembling Aldmer, more than any other race. And the Aldmer are direct descendants of the Et'Ada. While all mer races descended from the Aldmer, the High Elves are the most pure and unchanged form, whereas the other races have evolved into something entirely different.

And the Bretons do trace their ancestry back to the Aldmer, but their blood is heavily mixed with the blood of men. As a result, they are extremely resilient to magic, but not as skilled.
