What you need to do is look at comparative performance for all piston types.
The long-body Mooney wins hands down in terms of speed, fuel efficiency and range every time.
Having the gear hanging down significantly degrades performance at all speeds - period.
I love the feel of the acceleration I get when the Mooney gear tucks away into the wing - sweet!
Plus it is FIKI deiced and has the fully integrated G1000 (now with GFC 700 autopilot) as standard.
Problem is Mooney advertise only about 5% as much as Cirrus and their lean ad budget is matched by the limited column inches their aircraft receive in coverage.
If somebody farts at Cirrus it is headline news in Pilot/Flyer etc...
But if people want to fly the equivalent of a Ford Mondeo...
