That’s what I thought as well. The fan-less Air will just underclock the CPU in order to stay cool, so you’ll only get bursts of topspeed while the Pro with a fan can sustain the heat and thus the right clock speed for longer, which will give you more performance over time.

I have put in an order for a MacBook Pro M1

Air only if portability or its sleek design matters but pro every other time, maxed out on as much cpu and ram you can afford and at lest double what you ‘need’ on the SSD

Pro-you’ll get better specs and better cooling will mean longer periods of sustained workloads without throttling.
