Gaurs vs ATS: Which Noida project avoids possession delays?

Based in Dubai, I'm looking at Noida for investment. Gaurs Platinum Towers sounds tempting at that price point, but what about possession? ATS Pious Hideaways is ongoing, so risk zyada hai. I can't do site visits myself. Anyone faced delays with Gaursons projects before? Or is ATS worth the gamble for appreciation? Need a property manager, so rental potential bhi important hai. Which has better resale value down the line? Sahi hai?
