Dwarka Exp ROI vs Sector 49's safe bet

Dwarka Expressway completion ka Gurgaon real estate pe kya real impact hoga? I'm eyeing a 3BHK in Sector 49, solid ₹2.2 Cr. But for pure appreciation, should I consider properties further along Dwarka Exp, near Sectors 102-113? Global City ka effect bhi dekhna hai. From your experience, which offers better ROI?
