Well without doing the math and using the fact that we know a pocket pair is usually a slight favorite over 2 overcards it should be obvious that A2 is the favorite here.

Note that when the overcards hit, the pair only has 2 outs to win. On the other hand, when KQ hits A2 has 3 outs to improve.

So intuitively you should see that A2 is better off than a small pair against middle cards.
