Which Center Speaker - Polk or Bose?

Hi, Everyone,

I am a total newbie to surround sound, but I am looking at choosing between the following two center channels:

The Bose looks nicer as I am pairing it with some Bose 201 bookshelf speakers in the front. However, the Polk came with a system I bought (including the center, sub, receiver, and 5 surrounding speakers). The both have similar specs. I have heard how much difference a good sounding center channel speaker is, but I am torn between the aesthetics and the online reviews I've read. Some are trashing the Bose model.

I was looking at selling the Polk center and other 5 speakers for enough $ to buy the seemingly pricey Bose model.

Any advice? Many thanks.
