Resolution, colour fidelity, response time.

Phase-detect is generally faster, often much faster. Contrast-detect  
autofocus, if implemented well, can be more accurate.
Also, contrast detect AF requires having the sensor powered up.

If you are aiming for the "deep-blue sky" look, you will want to point the  

turn the polariser to match.

If you just want to see the polariser in action, look at an LCD through it  
while slowly turning it.
