Confused about builders for my Noida Ext 3BHK upgrade

₹1.5 crore for a 3BHK in Noida Extension feels steep, but I'm seriously considering upgrading from my 2BHK in Sector 78. I'm looking at projects by Godrej, ATS, and Gaursons. Has anyone dealt with them recently? I'm worried about project delays after hearing so many horror stories. Also, what's the actual construction quality like once you move in? Plaster cracks, seepage – is it a common issue? And how's their customer support if you need something post-booking? Not sure if the premium for some of these is really justified.
