Sunshine Helios carpet area justifies the price jump?

Currently in a 2BHK in Sector 75, thinking of upgrading. Ajnara Grand Heritage and Sunshine Helios are on my radar. But is the price jump to Helios worth it? Kya kisi ko pata hai about the carpet area efficiency in both? Already have a home loan, so EMI will be a big factor. Heard Helios has better amenities, but are they actually used or just for show? Which one offers better rental potential, long term? Honestly not sure which to pick.
