Well yeah, in other words, it shifts clunky. Decisively, sure, but clunky.
We can mask it with polite language all we want. Choose a word that makes it sound not as bad. Call it decisive. Call it feedback. End of the day all these are just code words for the truth which is it's less smooth compared to Shimano's shifting.
As mentioned this has all been beaten to death by hundreds of reviews for years.
