Rocket66:
Have a talk to some owners. Have a talk to a couple of service centres that maintain Cirrus Aircraft. Also, go for a flight in a Cirrus yourself. The above owners or the dealer would be happy to take you for a flight.
My guess is there must be a reason why the Cirrus SR20/SR22 series has been the best selling 4 seat aircraft for many years.
IF the C182 or A36 were seriously better, the sales figures would reflect that.
