I'm, however, not sure which one. I have 16" that was given to me by my employer (gonna quit the job, so will have to return it), but I never really worked off it. It's docked 99% to dual monitor setup.
If I get the 14" it will be the 2023 model, if I get the 16" it will be the 2021 model (odd price difference that makes 2021 14" more expensive than 2021 16", but the opposite in 2023 models, weird).
The rationale behind getting 16" is - bigger screen. On the other hand, I'm going to eventually settle back home and will probably keep the Macbook docked to a normal dual monitor station, so from that point of view, getting the 14" makes more sense.
One other consideration is that I mainly do development, and I do it in Neovim. Other than Neovim, I just use the browser, email, and sometimes photo editing software. And while it is true that 16" gives more screen real estate, I'm also not the person who has an IDE open with a terminal, file browser and whatever. I utilize Neovim and tmux heavily, and prefer to have one thing on a screen and use MacOS spaces/desktops feature.
What do you think?
14" has been plenty for me.
Getting a TWM like Amethyst helps a lot with the small real estate.
