Have tried both. Flying School & Aero Club.
The Aero Club wins hands down. At most flying schools you'll soon tire of giving your hard earned cash to a pack of infighting egomaniacs who are paid by the flight hour.
Join a club. You'll see where your money goes (not on maintaining a bunch of 30 year old Traumahawks). And you'll fly with a great bunch of people.
That's been my experiance.
