Well, technically he is correct since containers on osx actually run inside a Linux VM, adding some overhead. Obviously use whatever works for you, but containers on Linux is a different beast and besides better performance offer some other things that some people may find useful (e.g. zfs containers). Also, the number of moving parts is much fewer. You can run containers right on top of systemd if you want.
