Jim recently bought a Mac Mini to do freelance video editing. He also recently got a MacBook Pro laptop from work to do editing at home. He had to roll back to Mojave after problems in Catalina. Should he update to macOS Big Sur? Leo says no. Big Sur has problems right now, and if you're using your Apple products for working, there's no rush or advantage to upgrading the OS.
Big Sur is a huge change, and is primarily written for Apple Silicon Macs. So if there's no real need, why rush?
