Upgrade to 3BHK in Noida - worth the risk?

Currently in a 2BHK in Sector 74. Thinking of upgrading, but Noida's confusing. Gaursons Gaurs Platinum Towers keeps popping up. Has anyone dealt with Gaurs Group? I hear mixed reviews about construction quality after possession. Plaster cracks and seepage are my biggest fear, tbh. Already have a home loan, so EMI is a big factor. Is the price jump worth it for a Gaurs project versus someone else? What about hidden charges at possession? PLC and all that. Should I be worried about those with Gaurs? Or are there better builders in Noida for on-time delivery and fewer post-possession headaches? Not sure if I should take the plunge. Any advice?
