Ready to move is always better than under construction, right?

I'm based in Dubai, so can't easily check Noida projects. Nehra Lotus Avenue 2 is ready to move, but Antriksh Golf View II is completed. Kya Antriksh mein carpet area zyada hai? Is it worth the extra cost, or should I just stick with ready-to-move for peace of mind? Rental potential bhi dekhna hai.
