Is Catalina a good upgrade yet?

We're now past Catalina's midpoint: with four versions already released, there's only three more to go before we prepare for the first release of 10.16. That's a stark fact, that we're now at the point where the more cautious should consider whether they'll run 10.15.

Unusually for macOS, there are many Mac users with Catalina-compatible Macs who are no more able to upgrade now than they were back in October. These include the many who still have to rely on 32-bit apps, and those whose Mac doesn't start up from an SSD.

There's still a lot of trepidation about Catalina, even among the Apple faithful in popular podcasts like ATP.
