I would have loved a gifted school. The "honors" classes at my school were a joke. When I was a teenager, I had the chance to attend a gifted camp, which I loved, and I ended up attending a very rigorous, selective college, which I also loved. Being among your peers is wonderful, because you are no longer "the smart one"- everyone is smart, and you can talk about things which would get you weird looks in other company. School life is a lot less stressful, because you don't have to hide how much easier certain things are for you and pretend like you thought the test was much harder than it was. Plus, I had an easier time finding people of the same temperament as me, who liked doing the same types of things (like obsessing about certain TV shows). I have not had the same experience before or since.
