Which builders actually deliver on quality and time?

Been looking for 8 months now and it's getting exhausting. Fed up of renting, landlord raised rent again, so finally taking the plunge. I'm eyeing a 3BHK around Dwarka Expressway, budget ₹2.5 Cr. Builders like Godrej, M3M, and Emaar are on my list. Honestly, I'm worried about construction quality – seen too many horror stories about cracks and seepage right after possession. Also, what's their on-time delivery track record like? Heard some builders just keep delaying. Is it worth paying a premium for DLF or Sobha for better quality/timelines, or are others catching up?
