Seems like alot of you like AIMS which does have a good product and a good technical platform with Oracle and MSSequel however let down by the poor after-sales/support in our experience. Geneva, is perhaps too new on the block to have a track record especially in Europe - and with no office in Europe difficult to see how well it will be supported - but again platform is good - MSSequel. RM has been good and seems to have probably more than half the UK market but is let down on platform and development is snails pace - They are also closing UK office! Acrobat has its fans but platform and technically they are a dinosaur. Lufthansa has a good product with typical German efficiency! Others include Sabre (poor on crewing and megabucks), Atraxis, Mercury(SITA promoted),SBS, Borneman etc...
Thats about it... As others have said it's horses for courses and what you need - you may not need sophisticated optimisers. Keep in mind the after sales support - the best systems are useless if there is no support - ideally local support.
