I only had the metal frame for 1 year, we moved and put up an AG. It seemed to hold up well. It was definately easier to clean and dry to take down in the fall since it was still standing up. I personally think my metal frame was much sturdier than the donut I had before it. When the kids hung on the sides we weren't having to scream at them because they were letting water out! LOL If I were going that route again, I would definately go with the metal frame without hesitation. (I'd also take a good look at the new pumps that have a SWC integrated into them)
