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

Ajnara Ambrosia vs AVP AVS Orchard... I'm confused. Ambrosia is ready, right? AVS Orchard bhi ready to move hai, but it's pricier. Is it worth paying extra for AVS Orchard? Carpet area wise, kya scene hai? Honestly not sure which one gives more space. Also, maintenance charges ka kya hisab kitab hai? Has anyone lived in either? My parents keep saying ready possession is safer, but is the ROI better?
