Sector 129 overpriced? Prove me wrong!

Okay I'll be honest — I work in real estate but even I'm scratching my head at Sector 129 prices. I'm looking at 3BHKs, and honestly not sure if the price jump from, say, Sector 137 is justified. I see a lot of ATS projects there. Good builders, no doubt. But still... what's the big draw? Is it really worth the extra EMI? Heard the schools are decent, but are they *that* much better? And the metro connectivity is similar, right? Maybe it's just hype. I'm looking for real resident experiences. Is it actually peaceful living, or noisy construction all day? Anyone living there willing to give an honest review? What's the ground reality? Convince me! Hope someone can give some insights.
