Most of the time brighter sounding speakers such as the Motions are a benefit for HT. If music at high(ish) volume is going to be a large percentage of use, perhaps something with a little high end roll off would be better.
See if you can borrow your friend's motion 40s and hear how they sound in your room. Denon/Marantz are popular choices since most like Audyssey, especially the models with sub EQ. If the Audyssey app works, it makes for a nice system since you can alter the curve and frequency response of the room correction.
The 1000 series and up Yamahas are nice. They have a pretty good auto setup and a nice PEQ for manual tweaking.
