My use is very similar to Crusader. Samsung 55" 3D Smart HDTV, Blu-Ray Player, cable box, ethernet, with a 7.1 set up (front - Infinity SR 525 floor speakers, center - Yamaha NS AC3, rear - Yamaha NS A770 and Acoustimass 3 series III subwoofer system).
Video component is extremely important, so having 4K compatabilty is now something to consider. I liked the idea of the class D amp in the Pioneer, but since the entry level with 4K pass through is the SC-65 at $1,600 retail the cost factor is now an issue. Marantz SR5077 has 4K pass through and only $850.
I viewed numerous reviews of all units and found fewest complaints with the Marantz.
Not sure if I'm missing any other important factors.
