Honest,y Shock is better. The magic strikes faster and fewer enemies have defense against that element and in Skyrim it drains magicka, which makes it potent against mage-types.. If I had to choose between Fire or frost, I'd go Fire for several reasons. It also flies faster than Frost, can be used for survival (fire/light/heat/cooking/etc), and often comes with additional damage over time whereas Frost tends to just slow an enemy.
