Good morning, P. If you peruse the forum a bit, you might notice a commonality in receiver rec's. That would be that only a handful of units are worthy of their advertised power ratings. A receiver is about more than power, of course, features are important if you want HDMI , Bass management, etc.
However, Marantz, Nad Rotel H/K and Outlaw have been tested to meet power ratings, whereas others(Yamaha being very poor) are insufficient to high power tasks.
Based on power alone, the Marantz is better on paper, however you may wish to explore the other makes I mentioned and listen to them all before jumping in.
Personally, I will vouch for the power of Rotel and H/K. How they present themselves with your speakers in your room with your music is up to you.
Your mileage may vary.
These mosels are covered quite well in the receivers section.
