Are big builders like Prestige and Sobha truly reliable in Bengaluru?

Visited a couple of 3BHK projects in Sarjapur Road and Whitefield last weekend, mostly by Prestige and Godrej. I'm currently in a 2BHK and thinking of upgrading, but the price jump for a 3BHK is substantial, often ₹1.5 Cr+. Already have a home loan, so this is a big step. My main concern is construction quality – do these big builders like Prestige or Sobha really deliver on finishing, yaar? Heard stories about seepage and plaster issues post-possession. Also, on-time delivery track record kaisa hai? And what about hidden charges like PLC or maintenance deposits? Don't want any nasty surprises at handover. Any experiences with these builders in Bengaluru?
