Noida mein investment: Kingson Buildtech vs Sector 39?

Hey guys, I'm thinking of investing in Noida real estate. What's your take on Kingson Buildtech Pvt. Ltd.? I've heard mixed reviews. Kya kisi ne unke projects mein invest kiya hai? What's the expected ROI? Also, I'm considering Sector 39. How's the rental yield potential there? Which one is better for long-term appreciation, Kingson Buildtech projects or property in Sector 39? I'm also a bit worried about market volatility. Is it the right time to buy, ya phir wait karna chahiye? Mujhe advice chahiye. Has anyone experienced construction delays with Kingson? Not sure if it's worth the risk. What do you think?
