B&W Nautilus or Dali Euphonia

I'm Looking at this two Speaker for Hometheater application for a 7.1 set up. What speaker will you consider has the more potential for Hometheater? Which one would you prefer and why? In the B&W line I will consider the Nautilus 802 as main speaker.HTM1 for center, SCM1 for surround, On the Dali Euphonia I will consider MS4 as main, CS4 for center, RS3 for surround. Any imput will be highly appreciated.
