In general I agree with the premise in the article but as Fred said it’s very room dependent.
In my apartment (20 x 20) after much testing I settled on mains set to large and used LFE+Mains because it gave the best overall sound quality by having multiple bass sources and full range mains in proximity to my listening position.
In my house (21 x 13 + attached rooms) I’m using mains set to small with a crossover of 60Hz because room modes are not as much an issue with bass and the receiver is more taxed powering the mains farther away from my listening position.
The feature I like the most is having separate bass management settings for 2 channel vs multi-channel since I don’t use a sub for most music listening.
