Jaypee Greens: Is the premium worth it?

Okay, I'll say it, everyone glorifies Jaypee Greens, but nobody talks about the delays! Currently, I'm in a 2BHK. Thinking of upgrading, but is the price jump worth it? On-time delivery track record is worrying me. Has anyone experienced hidden charges at possession in Pebble Court? Kya aap logon ko pata hai about their RERA compliance? Change my mind. Already have a home loan, so bank approvals shouldn't be an issue, right? Mujhe advice chahiye!
