I have quite a bit of time in cherokee six types.
And a few hours in the C182
I much prefer the Cherokee six and its offspring (saratoga etc).
More comfortable, more passengers etc.
AS to comparing the C182 to a Cherokee Six with the 260 hp engine, it really isn't fair as there are very few of the 260's out there and they will be very, very old.
So, it all depends on the flying you do. Money must be put aside for a moment anyway.
Will you be flying from unimproved fields? (gravel etc) The 182 might be better, but then the 180 would be even better!
But just regular flying the roominess and flexibility as to payload, the Cherokee Six should win out.
Good luck.
Take a lesson in both and see which one you like better. Club seating in back is nice for the passengers.
