Still looking for the right replacement for my 2020 M1 13" which I stupidly bought with too little memory and a drive that's too small (I really need at least 16GB because I'm forced to use Office apps, and 1TB so I don't have to use Onedrive's awful search anymore and just keep my entire archive on my machine). The M1 CPU is almost always more than fast enough for me (maybe once a month I'll run into something that could use a little more speed).
I had almost decided on the 15" Air because the 14" Pro has a smaller screen and is a little heavier, and a lot more expensive. But with the new 14" M3, it's back to the drawing board... and I think I'd prefer the better screen, speakers, camera, and extra ports. The price difference is down to about €200 here in Europe.
Paradoxically, though, my Macbook spends most of its time closed with an external screen and camera on my desk. So I'm mostly looking at the difference while travelling, which is once every two months or so, and then it's really 15" and slightly lighter vs. 14" and slightly heavier. So I'm still undecided.
