I have Catalina on my work machine and Sierra on my personal one. Using Catalina at work hasn't really shown me any compelling reason to upgrade my personal machine, but it has given me several reasons not too (general stability, poor handling of external monitors, lack of forwards compatibility for apps I care about, etc)
