Ive flown the 400 in the states.
The handling is very good. The cockpit feels more compact than the cirrus.
I am surprised that he concluded its far superior, albeit you probably would if the comparison was with a 20.
Personally i think the handling of both a delight. The commonly heard criticism that the side stick is not designed for hand flying imo comes from those who havent hand flown the aircraft. However its fair to say many / most cirrus (and 400) pilots dont hand fly. These aircraft are about going distance in comfort.
Like it or not cirrus captured a moment in the ga industry. They make a good product, they market it well and its nice to fly. Then again its a privilege to fly most aircraft in this category and each will have those who reckon theirs is the best thing since sliced bread. Peterhs tb20 is a superb aircraft and if you want something that is as good as a cirrus without all the insurance and training issues and of course without the worries of a chute look no further.
