I've been to both ACFT and Min's, both pretty good but Min is the best. One or two of the instructors at acft are in the flying jacket with lots of badges brigade, which is always a worry.
Flew the Dec at acft, very nice machines used to fly them years ago but these ones are tidy. It also depends on what you are going there for, is it ppl or converting your 6000hr foreign cpl. If you are the latter then price and efficiency would rule me and if its initial training then a comfy relaxed atmosphere and price is important and Min's get the vote for that and she does not have more badges than a boy scout either. I also found acft quite slack on time keeping of the aircraft when you turn up for a flight, which is fine if they call you but in my case they did'nt.
But I reckon after years in the industry and many flight schools visited they are both good. fly with both if you are unsure and make a decision after you would not buy a car just by looking at one, you would drive a few.
