well.. for me,
pros:
-detachable cable
-smaller form factor
-matte finish
-the price
-braided cables

subjectives,
-tenkeyless
-green led
-blue switches
-font used
-shorter layout? windows key seems smaller

i don't think cons are needed as they are rather subjective as suggested above. those are all my personal opinions so some will not agree or completely disagree with me.

and i'll be getting one of this once i get rid of my current blackwidow expert
