Mohali projects: Investment ya hype?

Since January I've been shortlisting properties in Mohali for an upgrade from my 2BHK. Everyone glorifies projects like Birla Navya Drisha 1B Plot, but honestly, Alton Tatva Estates ka carpet area efficiency better lag raha. Birla ka naam hai, par kya actual builder track record aur future appreciation mein farak hai? Not sure if that premium for Birla is justified. Log kehte hain Alton Tatva Estates mein ROI achha milega, but long-term investment ke liye kaun sa sahi hai? Change my mind.
