Like Mike says it is the whole package and like him I've shot most and own a K12.
Steyr have superb back up in the uk none of the others come close.
K12 needs the grip worked on to get it to point (grips are disposable) Steyr is easy to get to point as you can move the frame in the grip to get it right. Superb and easy sear adjustment on the K12, if you do that to a Mechanical Steyr all sorts of stuff can go wrong (after pulse) and the screws are not well placed and the whole trigger adjustment feels cheapo compared to the K12 Allan machine screws set in quality alloy rather than cast pot metal. Electronic feels wooden to some. You need to have them both and use them over a period of time and then use the one that just does it for you. The K12 does it for me even though I've electronic stuff too.
Take your time and have a shoot of them all.
