Emaar Palm Heights Sector 77: Mivan construction worth it?

Just came across a video for Emaar Palm Heights in Sector 77, Gurgaon. It's a 3BHK+Study+Servant, 2000 sqft, west-facing balconies. Price 2.66 Crores onwards. What caught my eye was them mentioning Mivan construction. Honestly, is Mivan construction really that big of a deal for residential projects? I've heard mixed reviews. Also, 2.66 Cr onwards for Sector 77, Gurgaon feels a bit steep, ya nahi? What do you guys think about Mivan quality for homes, and is this price point justified for that area?
