I would be confident of receiving good instruction in Alaska or Minnesota, but not Florida (naming no names).
Depends what you're trying to achieve.
I got my FAA float-plane rating in Florida. I have to admit the training wasn't perfect, and I probably wouldn't have been a very safe float-plane pilot the day after I passed my test. I passed with exactly the minimum hours. The course was a fixed price regardless of the hours taken, and the examiner was an employee of the school, so it was in everyone's interests for me to pass.
However..... I actually had no intention of keeping current on floats after getting the rating. I had a fantastic time flying on floats, learnt lots - and I have something on my license to show for it. Now, 18 months on, I'm probably no less safe than the next float-plane pilot who is 18 months out of currency! So, in the grand scheme of things, the fact that my training was not the most thorough has made no difference. Had I been intending to walk away from the school, buy a float-plane and fly it, I would have insisted on more training, but that's not why I did the course.
