I've read these all (and the other threads), and I'll chime in. I do a ton of reading and writing for work (historian, archival sources, occasionally handwritten), so a better screen and a BIGGER screen are just better.
I've been using a m1 11", and it's fantastic. But my workflow just works so much better with more real estate. At home I run a 16" M1 MBP connected to 2x32" 4k monitors, and occasionally a third 27" in portrait. My phone is a 14 Pro Max. I travel about a quarter of the year, and so have the iPad as a second monitor.
So I've been on the fence, gone to the Apple Store twice to play with the different sizes. I'm going to order a 13 and try it with my workflow for a few days. With the weight reduction, I think it'll be great in the hand, and definitely liking the extra 20% larger screen when used as a second monitor on the road. And if after a few days it's too unwieldy, I'll return it for an 11".
Also going to pick up a Pencil and see how well it works with the apps I cycle through, none of which are on demo at the Apple Store.
