re:
Same resolution, different sizes. Screen tech is different, which one is subjective.
925:
16 GB memory with no SD. (32 GB model is rare)
Metal, non-removable back
Qi-charging option
Better camera no doubt
1320:
probably better battery?
Larger
8 GB + microSD option
performance-wise I expect them to be relatively on par.
I'd get the 925 because size and camera and smaller differences, but others beg to differ.
