2BHK to 3BHK upgrade — is it worth it?

Is JBMR The Oasis Residences actually good to live in, ya just good on paper? Everyone glorifies the fancy amenities in brochures, but nobody talks about whether they're even functional post-possession. I'm currently in a 2BHK; thinking of upgrading to a 3BHK here for ₹99L. My home loan already running, so this jump needs to be justified. The project delivery track record... is it really on time, ya sirf promises? Should I trust the builder's word for these "upcoming" facilities? Disagree? Tell me why.
