Greater Noida 6 Cr+ Plots: Builder Experience Kaisa Hai?

Wow, just found this video on those 500m luxury bungalow plots in Greater Noida, the ones above ₹6 Crore. Location advantages shown, especially Pari Chowk and Yamuna Expressway connectivity, seem pretty solid. It's a huge investment, right? I'm thinking about the builders behind these premium sectors. Video mein specific developer ka naam nahi hai. So, has anyone here bought plots from builders in these high-end Greater Noida areas? Unka track record, construction quality, aur possession delays kaise hain?
