Ready to move is tempting, but is it worth it?

I work in real estate but buying for myself is different, yaar. I'm looking at Amrapali Crystal Homes. Ready to move, which is a big plus. But those prices! 2.27 Cr se 3.59 Cr? Then I saw Designarch E Homes, completed but cheaper, 33.96L to 1.34 Cr. Big difference! Is the extra cost of Crystal Homes really justified? Carpet area wise, I'm hearing Designarch is more efficient. Plus, the OC is already in place so no risks. Crystal Homes, maybe the amenities are better? Honestly not sure. Has anyone compared these two projects closely? Which one would give better ROI in the long run? Am I missing something obvious?
