I think in general Catalina was missing flagship features. - The split of iTunes into Music, Podcasts and TV (and system integration for iOS synchronization/backup) didn't bring about significant user-visible benefits. I think there was an issue with content not being available in iTunes under 4k the was solved, and Dolby Atmos was added. - Catalina is not really a user-level feature. The apps which are created using Catalina aren't really draws - Find My is probably my most used, and I could just use the website if it wasn't an app. - Reminders got a big refactor and new functionality, but the in itself is a limited draw. - A few smaller changes to Notes, Photos, and Safari, but nothing I couldn't live without - Screen Time - perhaps useful in families, but my understanding is that the conceptual differences between iPhone usage and Mac usage weren't accommodated for. There was the delayed release, impact to polish, and removal of features like iCloud Folder Sharing (which I've indirectly been told were all the same issue - that folder sharing was not stable enough to be integrated into the tree and it impacted other development). It was a much rockier-than-normal update. You also have the anti-features of 32-bit support being removed, and additional privacy-consent-for-access prompts for screen sharing, sensitive folder access, etc. The prompts are IMHO overblown - they are one-time and many of them have gone away as software has been updated for Catalina (as in, there was no legitimate reason for some particular application to be scanning the Desktop to begin with). This doesn't change that there isn't a big draw. If there is a big feature for macOS Catalina, it would be SideCar. This adds a second screen to the Mac, it enables pencil usage, and perhaps even provides a slight bit more justification to Touch Bar functionality. This is still limited as it is an ecosystem feature - IMHO its real value comes when you are using an iPad Pro.
