I think you might be over thinking this a bit. Get the one that has the features you need or want. Both are good products. I had the Marantz SR5008 a few years back. Loved that receiver. Not one problem ever! It had Audyssey XT. Moved up to Atmos and wi-fi so bought a Denon AVR-X3400H because of XT32. It took a lot of effort to get good results with it. Also the Denon proofed to be a very buggy receiver right from the get go. It's good now but i am still not excited about the Denon as i was about the Marantz!
So I purchased a Pioneer SC-LX502 and VSX-LX503 last week. still have the Denon. Right now i am trying out the SC-LX502. So far I like it better then both the Marantz and Denon. Has class D amp( Direct energy HD amplifier) Runs extremly cool, Not even luke warm! Chromecast built-in, DTS play-Fi,Net radio, Version 4.1+LE bluetooth and a really really nice phone app that for me is worlds better then the Denon.
So far it's been bullet proof, No buggy issues. Firmware updates for Amazin music works flawless (which i used alot) and e-ARC. Receiver has been spot on, easy to calibrate and sounds awesome. Especially in 5.1 pure direct when playing my SACD's.
I really have no reason to open up the Pioneer VSX-L503 so it's going back sealed. It can drive up to 11.2 channels where the LX502 is stricty a 7.2 channel receiver like the Denon 3400H. If the LX503 had a Class D amp then i would have just bought it and not the LX502.
Make sure you think serious about buying a A/C infinity Aircom S6 to sit on top of the AVR if you buy a Marantz or Denon. Or have it sitting in a very open area rack.
