Noida investment: Parsvnath Developers or elsewhere?

I'm thinking of investing in Noida, maybe Sector 128. What's the rental yield potential like these days? Also, I've been considering Parsvnath Developers. Has anyone had experience with them? Kya ROI achha mil sakta hai? Or are there better builders for long-term gains? Mujhe advice chahiye on whether under-construction is worth the risk versus ready-to-move. What do you guys think?
