I have experienced the comfortmatic in two vans now both Euro 5. The 1st was 2.3L 150hp on a 4250 tonne van and the second in a 3.0L 180hp (I think) 4250 tonne van and there is one heck of a difference between the two. There is probably 30% less gear changes with the 3.0L with very similar economy. So given a choice then it would be the 3.0L everytime.
