I'm willing to bet it's easier to set up a Linux VM on a Chromebook than on a Mac. But the other side is that anything not explicitly requiring Linux will work natively in macOS, where you also get a nicer terminal. Like I've not needed a Linux VM in years, and the author doing web dev probably won't either.
Crostini is built into the Chromebook, vs macOS where I hear a different container solution every time someone asks about it. Colima is a new one to me. Maybe it works great and the others do too, but full 1P support is a step up.
