Without knowing what you are using for an amp or receiver, it is hard to give you a definite recommendation. Of the two that you listed, I would go with the Polks. I find that Polks do a good job across the board within their price range and if you look around you can score a pair of the TSi100 for under $200/ per pair.
If you can nudge your budget to $300, there are two excellent speakers that I have owned and used that would do a good job with your musical tastes:
Energy RC 10
Ascend Acoustics CBM 170 .
