Is Regal Emporia worth considering in Sector 164?

Been renting for years, fed up of landlord raising rent again! Finally taking the plunge and buying. Visited a Regal Emporia Infratech Pvt Ltd project in Sector 164 last week. Looked decent, but honestly not sure about the builder. Heard mixed reviews. EMI vs rent math is killing me, but scared of under-construction delays. Ready-to-move is pricier. Is it worth the extra cost for peace of mind? Anyone invested there? Any advice?
