Based on comments here, it seems that it's all about one's personal experience. For me...
Never a problem with my XB360.
OG Xbone won't read disks anymore
XB1S has to be restarted regularly to connect to the internet
PS4 Pro sounds like a jet engine
OG WiiU takes like 45 minutes to start playing a game
Now that I think of it, aside from the lack of a backlight on some old Nintendo handhelds, basically all of the complaints about hardware that I have are related to 8th gen systems.
