Can't decide on builder quality in Krishna Kunj

Honestly, I thought all builders were mostly the same, but Krishna Kunj mein project dekh ke I'm confused. Everyone glorifies Balaji Group, but kya Madhav Group ya Galaxy ki construction quality aur post-possession service ka koi real talk nahi karta? Are we just paying for brand name? Maintenance charges aur RWA effectiveness ka kya scene hai? Change my mind.
