Noida Expressway: Real talk on daily life?

After years of advising clients, I'm looking at properties along Noida Expressway, especially Sector 126. Brochures make it sound great. But ground reality mein commute aur daily life kaisi hai? Kya traffic sach mein itna smooth hai, ya hidden issues hain jo sales guys nahi batate? Residents ka honest opinion chahiye before I decide.
