I switched from Mac to Linux a few years back, haven't regretted it for a second (well, there were a few seconds in there that were touch-and-go).

I now run a tiling window manager (i3wm) on a Debian distro (PureOS, came with the laptop) and I'm enjoying it immensely.

I still use an external Apple keyboard (a magic keyboard from 2015 - y'know, when they were good hehe). The trackpad has never been quite up to the Mac's standard, so I use an external mouse too. But I was using an external keyboard and mouse even on the MBP, so no change there (just the option to switch to trackpad isn't as awesome).
