Dridha Elite vs Unnati Vesta: Carpet Area ka scene kya hai?

Currently in a 2BHK in Noida, thinking of upgrading. Dridha Elite looks good, but Unnati Vesta Suites is ready to move. Has anyone compared carpet area in both? Is the extra cost for Dridha worth it for potentially more space? Also, kya kisi ko pata hai about actual maintenance charges in Vesta?
