Noida property purchase: Amrapali nightmares still haunting me!

Since January I've been seriously looking to buy in Noida. Honestly, the Amrapali mess still makes me nervous about builders. I'm mostly considering projects in Sector 150. My budget is around 80L for a 2BHK. I've been researching Godrej and ATS. ATS Green projects look good, but I heard some stories about delayed possessions even now. Godrej seems more reliable on that front. But my parents keep saying to check for hidden charges at possession. Is it true that some builders add extra PLC or EDC costs that weren't initially disclosed? Also, how responsive are their customer support teams post-booking? Any insights would be helpful!
