Having flown in both aircraft types, I'd say there is a huge gulf between the Cirrus and the Bonanza, beyond the legislation. I'd want 10-15 hours in a Bonanza before I felt remotely comfortable handling it. I've seen even experienced Bonanza pilots pushing/pulling the wrong plunger control for prop/mixture/throttle. They are a 'legacy' ergonomic nightmare. Great go-places machines especially with a turbo and oxygen.
On the other hand, you really need the autopilot in both types to be able to look after the navigation, especially I'd say in the Cirrus. In view of the number of incidents' accidents involving autopilots, maybe it should be included in the above list.
