Docker is "Runs on any Linux, mostly, if you have a new enough kernel" meaning it packages a big VM anyway for Windows and macOS
VMs are "Runs on anything! ... Sorta, mostly, if you have VM acceleration" meaning you have to pick a VM software and hope the VM doesn't crash for no reason. (I have real bad luck with UTM and VirtualBox on my Macbook host for some reason.)
All I want is everything - An APE-like program that runs on any OS, maybe has shims for slightly-old kernels, doesn't need a big installation step, and runs any useful guest OS. (i.e. Linux)
