The better screen and better keyboard are probably the most day to day practical reasons to upgrade. But that’s countered by the extra weight and thickness of the Pro, too. So it’s really a choice of mobility versus usage ergonomics.

The Pro is also fan cooled, but with Apple Silicon I’m not sure that matters all that much at this performance band. If you need fan cooled performance you probably want to start thinking about a Pro level SoC, at which point you’re all in on a Pro machine anyway.
