Ready possession is king — under-construction is too risky now

Currently in a 2BHK in Sector 75, thinking of upgrading. AKS Rose 4 looks tempting price-wise, but it's under construction in Greater Noida. Honestly not sure if it's worth the risk. I've heard stories of possession delays. Soni Hardik Tower is ready to move, which is a big plus. But is the price jump worth it? Also, what's the carpet area efficiency like in these projects? I'm seeing different numbers online. Don't want to end up paying a premium for unusable space. Which one would you guys recommend for a family actually moving in, not just investment? Already have a home loan, so EMI is a big factor. Is it better to pay a bit more for peace of mind with Soni Hardik? Tell me your experiences!
