On my 2016 MBP, I also map CapsLock -> Control and Left_Control to ESC. It's goofy having ESC down there but I need a physical key as I do not look at the keyboard while typing in vim - there is no haptic feedback from the glass surface.

I am 50/50 VIM / EMacs so the it's important for my control key to be on the home row.

I'm not sure why keyboards even have caps lock. It's rude in chat right :-) I started with Sun keyboards where control was on the home row. I guess if one spends hours typing long capitalized acronyms daily, then it makes sense.

It's personal preference in the end. I certainly wont buy another MBP - my 2016 has had 4 trips to the Apple store since I bought it for key replacements.
