Boomerang Residences: worth double Lotus Panache?

Just moved into Noida, and honestly not sure about property valuations. Lotus Panache is around ₹2.6 Cr, but Jaypee Boomerang is almost ₹5.7 Cr. Is it *really* worth double? Boomerang is ready to move, which is a huge plus, unlike the under-construction gamble. Panache has better green space, I think. The location is similar though. Higher maintenance costs for Boomerang, I assume? What's the community think? Which one would you pick and why?
