macos – Will Macbook Air 2017 benefit from Catalina upgrade?

I’m running Mojave on my Macbook Air (2017) and was wondering if anyone can recommend (or not) upgrading to Catalina now that 10.15.7 seems to be stable release.

I’m not using any 32bit apps, so no problems there.

However, is it worth actually upgrading? I know I can’t use certain features (such as the battery health or sidecar), but should I do it for security, etc?

What are the experiences of other MBA 2017 owners after upgrade? Has anyone experienced slowdowns? Is anything actually better? Or should I just stick with Good Ol’ Mojave?
