Ghost and Trackers do very different thinks, so not really either or. Ghost prevents the car being started, so should be first. A Tracker is only going to tell you (if it’s not blocked or removed) where it’s been taken too. Which is a bit late really.
As many are taken by scanning for keyless entry signals, or plugging into the OBD port a Ghost is the way to prevent it. Only option left is physically towing or picking it up, which is rare. So that’s where GM’s security chain is good deterrent and physical barrier.
