Sohna 2BHK: Is floor premium a good investment?

Are floor-rise premiums actually worth it in Sohna, especially for a 2BHK in Sector 57? I'm looking at AS Estate and their PLC seems steep for a higher floor. Honestly not sure if it makes sense long-term for a first home. Also, does anyone know if secondary market deals give more room for negotiation compared to new projects here? My budget's around ₹1.2 Cr. Trying to get the best value without overpaying for a higher floor. Any advice on what to look out for?
