I use a 13" MBA (M3/16GB/1TB). It's basically a replacement for my iPad (was using a 12.9 M1 iPad Pro) and also acts as a backup Mac for me. My old backup was a 2016 15" MBP with some butterfly keyboard keys that didn't work.
It's very portable and I can take it with me wherever I need to use it. It is also more versatile compared to the more limited iPad Pro (and much better than the old Intel/butterfly keyboard MBP).
I considered the bigger 15", but I wanted something more portable and closer in size to my previous iPad Pro. Also my main Mac is already a 16" MBP (M3 Max/48GB/1TB) so when I need the bigger screen/ports/more power.
