Well for the German, French & Turkish air forces it's good enough, it has the transport capabilities a little less than the "Fat Albert" C-130. As the military of those mentioned tend towards light rapid reaction forces, unlike America, Russia etc who rely on large ground forces & conventional mass arrays of Armour, Infantry & Artillery in a war fighting capacity, I reckon the Transall C-160 is aptly fit for purpose.
