MMD Provica Homes: 3BHK layout vs. actual living space

Okay I'll be honest — MMD Provica Homes ka 3BHK layout dekh ke I'm confused. My current 2BHK sometimes feels more spacious. Is this 'usable space' trick common? How's the actual daily life there? Noise, air quality? Is the price jump from my 2BHK worth it for the real living experience?
