ATS Homekraft Pious Orchards: Too good to be true?

Since January I've been digging into ATS and Godrej. I work in real estate but buying for myself is different, right? ATS Homekraft Pious Orchards is tempting, but the price seems low. What's the catch? Godrej Jardinia is pricier, but maybe safer? Heard ATS customer support is slow after booking. Anyone faced hidden charges with ATS at possession? Matlab, PLC wagera. Is it worth saving some money or going with a bigger brand name? Help!
