Mahagun Mantra Villament vs Lotus Greens Isle - Noida mein kaunsa better?

Guys, I'm confused between Mahagun Mantra Villament and Lotus Greens Isle in Noida. Lotus Greens is ready to move, which is a plus, but the price is crazy high! Almost 14-19 Crore! Mahagun is cheaper, around 2-2.5 Cr. What do you think, is Lotus Greens worth that much more? Kya kisi ko pata hai about the construction quality of both? Also, anyone have an idea about the ROI potential for Lotus Greens considering the high price? Which one would you recommend for investment in Noida? I'm really looking for some advice. Mujhe pata chahiye! Has anyone experienced living in either of these?
