Finally buying in Noida - Unitech vs Eldeco confused!

Been renting for 5 years, landlord ne phir rent badha diya! I'm done. Unitech Unihomes 2 and Eldeco Ananda dono ready to move hai, that's a big plus. But Unitech's price seems lower. Is it worth the risk though? Anyone living in either? Carpet area kitna milta hai actually? Plus, resale value mein kaunsa better rahega? Socha tha EMI rent se kam hoga, but total cost dekh ke dar lag raha hai. Any advice?
