Noida Investment: Indiabulls Estate vs. Others?

Hi all, I'm considering investing in Noida. What do you think about Indiabulls Estate? Has anyone experienced their projects? Also, kya kisi ko Sector 155 mein returns ke bare mein pata hai? Is it a good area for investment? I'm also wondering about rental yield potential in Noida Extension. Which one is better for long-term appreciation? Mujhe advice chahiye regarding current market conditions. Thanks!
