I could be wrong, but it seems like someone who is happy to frequently switch between macOS, Linux & Windows is probably not actually taking advantage of all the features of any of them, and hence is not actually terribly productive (assuming arguendo that those features actually aid productivity).

For my part, I use emacs on Linux because I believe the power of computers is in crafting a personalised productivity enhancer. Free software which can be customised down to a very low level is part of that.
