The 42s ok but with a lot of hours in both the 42 and a cirrus i have to conclude the cirrus is better. Its faster, the cabin is more comfortable, the ride a lot better and the performance more sprightly. The best thing the 42 has going for it is how quiet and smooth the engines are compared with lycomings best.
Frankly for either to be better they would need to be pressurised or another 50 knots found otherwise it is all symantics.
