Thanks all
I do not want to mention which systems are specificly being looked at on this forum at this time, but we are also interested in data production to stimulate other systems like lighting, RIMCAS, AFDAS etc etc as well as to produce revenue generators and KPI monitoring for the airport as a whole. (this comment may spark a whole other can of worms)
You have all given me insight into my origional question though; it depends who you are and what your background and exposure to different systems is.
Its all valid stuff, thanks for the thoughts.
