Builder hidden charges in Noida Extension are getting ridiculous.

Okay, I'll be honest — buying property for myself is way harder than selling it for others. I'm looking at Noida Extension, specifically projects by Godrej, ATS, Gaursons, and ACE. Matlab, I know the drill, but the hidden charges game (PLC, EDC) is next level with some. Has anyone faced crazy surprises at possession time with these guys? Also, construction quality ka kya haal hai after a year or two? Plaster cracks, seepage, finishing issues... I'm trying to avoid a future headache. Who's actually transparent and delivers good quality in Noida Extension?
