Jaypee Greens ya Supertech - Which is better in Noida?

Guys, I'm confused between Jaypee Greens and Supertech for investment in Noida. What do you think about their project delivery timelines? Has anyone experienced delays with either of them? Also, which one offers better after-sales service, especially maintenance? Kya aap logon ko pata hai about the resale value of their properties? Mujhe advice chahiye. I'm looking for long-term ROI. Which one would you recommend and why? Any suggestions?
