Sector 124 upgrade: Is the premium justified?

Thinking of upgrading to a 3BHK or maybe even a villa in Sector 124. Currently in a 2BHK in Sector 75, so familiar with Noida life. But Sector 124 prices are high! Is the price jump really worth it? Has anyone living there faced major power cut issues? Sector 75 mein toh electricity kabhi kabhi chali jati hai, but heard 124 is better. Also, what's the water supply like? Municipal water sufficient hai ya tanker lagwana padega? Already have a home loan, so EMI will increase a lot. Is the investment potential good enough to justify the extra cost? What's the resale value like in 3-5 years? Should I just stick with my current place? Honestly not sure what to do.
