Premium builder quality in Bengaluru: myth or reality?

Is Prestige quality truly superior, or are we just paying for the brand name in Bengaluru? Rent dete dete thak gaya hu yaar, Whitefield mein. Landlord ne rent phir badha diya. Planning to finally buy a 2BHK, around 1.2 Cr budget, maybe Sarjapur Road ya Yelahanka. Everyone glorifies Prestige and Sobha for 'premium' but I've heard so many stories about finishing issues and post-possession headaches. Builders like Brigade, Godrej, Puravankara... are they any different? Matlab, construction quality mein kitna real difference hai? Also, on-time delivery. Is it even a thing anymore? And customer support after booking, does anyone actually respond? Not sure if the extra cost for these 'top tier' builders actually guarantees peace of mind. Change my mind if I'm wrong.
