It depends on what you want to do. If you want to extract information from a specific network. maybe custom firmware is a good option.
If you want to just disable a very large number of machines to create economic damage or cripple infrastructure, a hardware implant would do just fine. And you wouldn't need to be very careful as to where it ends - if you make enough of them, they'll be everywhere.
If 1% of all MacBooks have a similar backdoor, there are about a dozen at my building.
