Builder timelines for ongoing projects are a joke, right?

Honestly, I've been looking to upgrade my 2BHK in Sector 70 for months now, and it's a headache. Signature Global Park 1 in Mohali caught my eye for a 3BHK, but I'm super skeptical about the possession timelines. They say 'ongoing', but builder ke promises pe kitna trust karein, pata nahi. My current home loan is almost done, so I don't want to get stuck with delays on a new one. Has anyone here bought there or knows someone who did? What's the real ground reality with their project delivery? Also, carpet area to price ratio kaisa hai? Online plans dekhe hain, but actual space feel alag hota hai. Does it feel spacious for a 3BHK, ya just on paper? Not sure if the premium is justified for the actual living space. Any insights on their project-delivery history or carpet area efficiency would be great.
