Jaypee Pavilion Height 4 vs UCHDL Trucia - Which to choose?

Hi guys, I'm confused between Jaypee and UCHDL. Jaypee is under construction, but Trucia is ready to move. Kya Jaypee mein investment karna safe rahega? UCHDL ka resale value kaisa hai? Which one has better connectivity? I'm mainly looking for good ROI and rental income. Mujhe advice chahiye! What do you think?
