In this case, it's obvious that while Topuria is decapitating the best fighters in his divisions, a performance like Chimaev's is boring.
The comparison is instinctive and unconscious, just as the adrenaline rush when one fighter puts the other under the kind of pressure that makes you expect the referee to intervene at any moment.
We can play the philosophers of the most infinitesimal details, but we can't fool our instincts, and a match like DDP Chimaev's might generate anxiety (and a consequent sense of liberation) in their fans, but it doesn't generate the exaltation, amazement, and jolts down the spine that a match where the fighters fight to the finish.
I don't like creating strawmen, but it seems strange to me that those who experience certain sensations in front of a finish or a fight fought blow for blow forget that these are the sensations that make us follow combat sports; appreciating the subtleties is fine, it's a fun aspect of the initial stages in which you discover MMA, but at a certain point the student phase ends and you just want to enjoy something that arouses sensations strong enough to make you come back for another fight.
