Green arrow Snapsort recommends the Pentax K-5. This recommendation, however, should be taken with a grain of salt since it doesn't always make sense to compare a entry-level DSLR with a pro DSLR.

You never add the the score on Sony for
1- More focus points 19 vs 11
2- Continuous video focus
3- Slightly more cross-type focus points 11 vs 9
4- Supports 24p
5- Takes 3D photos
6- Video autofocus
7- Better maximum light sensitivity

These few points are indeed make the Sony A77 better than K5. As I had both camera + nikon D7000
