Still wary about RERA, even after two buys

Honestly, after two properties, I'm still wary about RERA enforcement. I'm eyeing a potential investment in DLF Luxury Floors, maybe something on Golf Course Road. How do you *really* verify a builder's legal track record beyond just their RERA registration? Ambience Group has a reputation, sure, but even big names can have hidden issues. Are RERA complaints truly effective for investors, or is it mostly on paper? I need to know the actual ground reality for due diligence.
