I swear by 13 inch but I know I'm in a minority. I don't need a huge screen for my work. I like to look at code without bending my neck left and right all day long and if I need to multi task I four finger swipe left or right and feel extremely productive this way for many years now :)
EDIT:
I shall say I had an 8GB intel MBP before and 8GB was just about enough for everything including Docker.
13 really is the perfect size. I had a 16 inch forever before it because that is the size you needed if you wanted a capable enough computer to do what I needed. Now I can get a $1,200 computer that works better than my old $3,200+ computer.
I have fallen in love with the 13" size. I still have my 16" computer and I pulled it out the other day and it looked comically large on my lap. It seriously felt ridiculous. I couldn't believe that was my standard for so long. The 13" is still good enough to do most anything, but small enough to really be portable. My mom has an 11" air and it feels like a kids toy in my lap, too small for my liking. But the 13" MBP is right in that Goldilocks zone.
I will admit I turn down screen scaling down to minimum to get more stuff on the screen. The default screen scaling state makes things quite large out of the box.
I was using the 16" MBP before this but having gotten used to the 13" that now feels ridiculously huge. It helps that I'm not using XCode much though. That really wants a lot of screen real estate.
