It does not matter what the program is - if it adequately meets the needs of your child, then it is a great program. Being in a GT environment where some kids are academically stronger and smarter and quicker than my son taught him humility and the fact that no matter how good you are, there will always be someone better. He is not hothoused - he has instead transitioned from a child who was considered "the smartest" to a child who has to work hard in order to keep up with some kids in his class room. Now, he frequently stands up and speaks his opinions in class rather than choosing to dumb down and blend in and he works hard because things no longer come easily to him.
And he meets a lot of other kids by playing after school sports and also in our social circle - even though most are not academically as advanced as him, he still has things to learn from them - we are a non-TV family with no exposure to popular media and electronic games - so, he does not feel elitist when interacting with them - rather, he feels that they have a lot to teach him about popular culture!
Before you relocate, I would caution you to do the due diligence on the school choices - shadow them, talk to other parents, ask the gifted co-ordinator about what they can do for your children etc - because in our experience, many times, what looked good on paper did not turn out as we expected.
Good luck.
