About drivers: You are right... but things get a lot lot more messy if your specific USB driver is not maintained in the Linux Kernel.

I have the opposite experience with memory pressure (speaking only about desktop here). macOS (& Windows) do memory compression by default and most of Linuxes I know don't do that by default. I also have the feeling that at least desktop Linux get's incredible slow when you run out of memory and swapping begins (never encountered similar amount of slowliness on Windows or macOS with low memory).

Regarding container technology and macOS. If you are into docker checkout latest dlite beta: https://github.com/nlf/dlite/releases It runs docker on Kernel virtualization level on macOS with xhyve without the need of VirtualBox etc.
