What nobody tells you about builder reputation in Noida

Spent the whole Sunday checking out options in Noida. I'm looking at Eldeco Magnolia Park, which is ready, and Dasnac Westminster, still upcoming. My biggest concern is the builder trust factor. Eldeco has a long track record, but Dasnac, especially for Westminster at ₹7.5 Cr, feels like a huge leap. Are they known for consistent delivery quality? Also, I'm worried about the investor vs end-user ratio. For a high-end project like Westminster, won't it attract mostly investors? That makes me uneasy about potential 'ghost society' vibes. Magnolia Park feels more settled. What's the rental potential like for both? Will Dasnac actually command that high rent in 5 years? Any first-hand experiences with either builder's RWA or construction quality?
