Noida investment: Sector 120 or somewhere else?

Guys, I'm thinking of investing in Noida. What do you think about Sector 120? Heard S & U Buildtech Pvt Ltd has some projects there. Is it a good builder? Kya ROI achha milega? Or should I look at other areas for better appreciation? Also, what's the best time to buy property in Noida right now? Market conditions kaise hain? Mujhe advice chahiye yaar.
