Noida investment: Which sectors are actually delivering?

Budget finalised, loan pre-approved — but honestly, I'm completely stuck on which Noida sector. I'm based in Dubai, so visiting is tough. Is Sector 150 or 137 genuinely seeing appreciation from Jewar Airport's impact? How reliable are the rental yields builders claim for NRI investors? I can't manage it myself, so what's the ground reality for returns after property manager fees? Legal clarity for absentee owners is also a big worry.
