Which Noida builder offers better value, Gaurs or ATS?

I'm considering investing in Noida real estate. Gaurs and ATS seem popular, but which one offers better value for money? Has anyone compared their pricing per sqft and payment plans recently? I'm also curious about their on-time delivery record. Kya aap logon ko pata hai which one is more reliable with project timelines? Any experiences with their customer service? I'm looking for genuine advice before making a decision. Thanks!
