The best advice here is to pick the one YOU like best. Go listen to them more... have the dealer set them up properly... don't be afraid to ask them to do this. If you are going to spend that kind of money on speakers, then they'll do it. I also recommend listening to more than just one or two movie chapters. Spend some time with them before you decide.
As for my taste in sound, the Paradigms are a clearly superior choice. The Klipsch literally hurt my ears... hence my recommendation to spend some time with them. The initial impression of the Klipsch (to me) was WOW... very dynamic. After spending about 20 minutes listening to them, however, I needed aspirin and wanted to rip the horns out of them. That doesn't mean that they're bad speakers, they just weren't right for me. Had I purely went on first impressions, however, I would have probably made a poor choice for me. At very least, get the speakers from a dealer that would allow for a swap if you get the speakers home for a little while and decide you don't really care for it as much as you thought you would.
