onkyo vs. Marantz A/V recievers which better?

I am looking at purchasing a HT receiever (7.1). I am down to two models: Onkyo TX-SR804 or Marantz SR5001. The price point are about equal. I am new to HT scene, and not sure which is best to purchase? My listening will be 90% movies, and look forward to creating a second zone that doesn't require an external receiver. Speakers B&W 601, 603, and LCR600 Series 3
