I only have experience with the Canadian system called NEXUS (of which I am a member) and the US system referred to a Global Entry (to which I have access).

Never had to use automated border control in the EU yet during my travels.

My only comment is security based. The US and Canadian systems use biometrics (eye retina scans and/or fingreprints) which are essential for security IMHO. I hope the EU would have the political will to use the same.
