I picked the Air after looking at them side by side. I couldn’t tell too much difference in screen quality and the extra inch is very noticeable and usable.
Most of my work is email, PowerPoint, Teams meetings, web apps, and spreadsheets. For me, extra screen real estate is more important than darker blacks.
I also liked the feel of the keyboard (a bit shorter, easier stroke to my feel) when typing. And I travel a good deal for work and it is thinner.
If you need more power for your work stream, I can see the Pro making sense. I thought about it.
But the Air was a better fit for me. I ordered last week.
