Noida Extension Gated Community: What's the real ground reality?

Honestly, after years of renting and my landlord raising rent again, I'm finally taking the plunge to buy in Noida Extension. Focusing on the 'Gated Community' corridor. Brochures sab achha dikhate hain, but what's the actual ground reality for daily living and commute? I'm doing the EMI vs rent math, but hidden costs worry me. Many projects highlight amenities then hit you with high PLC for specific floors/views. Is that common? Morning traffic towards Delhi kaisa hai? People living there, how's water, electricity, internet? Any lesser-known tips or red flags during site visits? Need honest experiences.
