I have previously worked for Airways and a couple of other ATO's
If I were to categorize the ATO's that I have worked for or have reasonable knowledge of, using the analogy of Cars:
L3, FTE Jerez and CAE Oxford would be in the luxury market (Mercedes, BMW, Jaguar with associated dealer support), More expensive but you get a much better and more enjoyable ride and have a greater chance of getting to your destination on time and in one piece, looking like a businessman ready for work.
Airways - A Ford Escort with a respray, Carlos Fandango wheels, Furry dice, Air horns and tinted windows, you might get there eventually(not necessarily on time), without the same level of comfort, sorting out your own repairs en-route, tired and stressed, looking like Del Boy.
