Construction-linked plans are just a builder's cash grab

Budget finalised, loan pre-approved for a 2BHK in Whitefield. Builders like LGCL push construction-linked plans hard. Yaar, I know super area vs carpet area games. But paying upfront vs construction-linked? Not sure which has fewer hidden catches. Mera experience toh kehta hai kuch na kuch toh nikalta hi hai baad mein. Is it ever truly transparent?
