Ajnara Grand Heritage: Luxury tag hides high maintenance?

I work in real estate but buying for myself is different, especially in Noida. I'm looking at ABCZ East Platinum and Ajnara Grand Heritage. The price difference is huge. Ajnara is obviously positioned as 'luxury', but is it worth the extra crore? Has anyone living there seen sky-high maintenance charges later? Off the record, I've heard horror stories about promised amenities not materializing. ABCZ is completed but smaller. I know what builders don't tell you about carpet area vs super area games. Is Ajnara really giving you more usable space for that price, or just more marble? Should I just go with the smaller but ready ABCZ? Kya kisi ko pata hai resale value potential for both?
