I've owned over 50 AVRs. Personally, I like the Denon and Yamaha the most. Denon seems to have the cleanest SQ, and best room correction system. While yamaha has the best reliability, fastest phone app remote, and the proprietary room correction is decent.
I'm currently using the following
main system - Denon AVR-x2600h
Bedroom system - Yamaha RX-v683
Home gym system - Yamaha TSR-5790BL
I have the following in storage
Onkyo TX-RZ820 - really good amp, poor room correction
Yamaha RX-Z7 - good all around, limited to 1080p, and only 5 HDMI inputs including front input.
