Prestige, Sobha, Brigade: real-world experience for quality & delivery?

₹1.8 crore for a 3BHK on Sarjapur Road feels like a stretch, honestly. Looking at Prestige, Sobha, and Brigade for my next investment. From my experience, delivery delays are common, but kuch builders toh hadd kar dete hain. Concerned about construction quality post-possession. Plaster cracks, seepage, you know? Is Prestige ka QC abhi bhi top-notch hai? Sobha ka word-of-mouth reputation for finishing, does it hold up? For a long-term hold (5-7 saal), which one has better overall builder reputation? Not sure if Puravankara is even in the same league for quality in North Bengaluru.
