RERA is just a paper tiger for project delays, right?

Been renting for years and finally taking the plunge in Noida Extension. My landlord just raised rent again, so I'm done with that. I'm looking at 2BHKs, maybe around ₹70-80L. But the legal side of things... it's stressing me out. How reliable is RERA for actual project delays? Like, if a builder like Shree Balaji Enterprises or even Paradise Green Plaza delays, what are our real options? Also, what red flags should I absolutely look for in the builder-buyer agreement? I'm worried about getting stuck with unfair clauses.
