I also wanted to mention after reading the last post that school isn't perfect, but it also isn't terrible. I don't know that perfect is out there to be had. I'm not even sure if perfectly average kids find school to be a perfect fit for their needs and desires.
Personality also made a difference in the choices we made for our kids. Our oldest is unusually driven and focused and was clearly miserable early in elementary to the point that I homeschooled her briefly b/c I was worried about her mental health. Our youngest probably would have been reasonably happy with neither her HG-ness (new word here - lol) nor her 2e aspects recognized. She's more content to just coast along. I do think that the amount of GT participation that she's done has been better for her than nothing though.
