Indiabulls vs Mahagun in Noida - Which is better?

Hi everyone, I'm looking to invest in Noida. I've been considering Indiabulls Enigma and Mahagun Mantra I. What do you think about Indiabulls Estate's reputation? Has anyone experienced their project delivery timelines? Mahagun ka track record kaisa hai compared to Indiabulls? Which one is better for investment, considering ROI? Kya kisi ne recently property kharidi hai in projects mein? Mujhe advice chahiye regarding their customer service. Which one has better after-sales support? I'm also concerned about the quality of construction. Has anyone faced issues with Mahagun's construction quality? Which one would you recommend based on your experience? I'm confused. Thanks!
