Builder's promises about construction quality are mostly marketing talk, change my mind.

Just moved into a project in Sohna, and already seeing minor issues. For those who bought from DLF, M3M ya Emaar in Sohna, what's your take on their construction quality after possession? Like, actual plaster cracks or seepage? Aur post-possession maintenance charges kitne reasonable hain? Godrej aur Sobha ka kya scene hai? Kya Signature Global ka delivery track record Sohna mein sahi hai ya bas delays hote hain?
