Noida property: Eldeco delayed my friend, should I avoid?

Okay I'll be honest – I'm confused about builders in Noida. Heard Eldeco Swagatam had possession delays; a friend suffered a lot. Is it a common problem? I'm looking at resale in that area. What's the actual construction quality like after a few years? I've seen some projects with major seepage issues. Should I focus on projects where RWA formation is already done? Investment ke liye sahi rahega ya nahi?
