Possession delay with Supertech? Change my mind.

Currently in a 2BHK in Sector 75, thinking of upgrading. Everyone glorifies Supertech, but nobody talks about the possession delays. I've heard horror stories about projects being years behind schedule. Is the price jump worth it if you're constantly chasing them for possession? Already have a home loan, so EMIs are a big concern. Change my mind. Disagree? Tell me why.
