GLS Avenue 51 aur St. Patricks, kiska construction reliable hai?

Budget finalised, loan pre-approved – ab bas builder decide karna hai. Main real estate mein hoon, but apne liye lena is different yaar, I know what builders don't tell you. GLS Infra ka GLS Avenue 51 aur St. Patricks Reality ka Central Park Bignonia Towers, dono options mein hain. Gurugram mein inka construction quality kaisa hai? Hidden charges bahut lagate hain kya possession pe? Aur booking ke baad customer support bhi theek se milta hai ya nahi? Kaunsa zyada reliable hai?
