Noida builder promises are too good to be true, right?

My parents keep saying all builders are the same, but surely there's a difference? I'm looking at projects in Sector 150, and honestly, the amenities some are promising seem insane. Like, is that all just marketing? I heard Supertech kaafi late dete hain possession, is that still true? And what about hidden charges? My friend bought a flat, and PLC ne uski band baja di. Does anyone have experience with actual carpet area vs advertised for ATS vs Godrej? I'm so confused ab samajh nahi aa raha. Which builder is actually better with RERA compliance and refunds if things go south? Any tips? Hope this helps someone avoid my mistakes.
