Ghost vs Pandora?

My car was stolen recently and I fitted a Ghost 2.0 to its replacement perceiving it to be the best. It has thwarted a few local thefts with other cars fitted with it.

A neighbours Range Rover was recently however stolen with a Ghost fitted, thief was under the bonnet for a minute or so. Clearly knew what they were doing / how to find the Ghost. Appreciate this is very rare statistically.

Googled a few alternatives and Pandoras seem to be well regarded.

Anyone have a technical view on them? Views on ghost fitted cars being stolen also appreciated.
