Ghaziabad investors, what's your take on project delivery consistency?

Builder delivery timelines are usually just marketing fluff, especially in Ghaziabad. I'm looking at Basant Krishna Vatika as an investment, it's completed now. What's the real capital appreciation trend been like since its launch? I know builders often show inflated figures. Also, how reliable is the builder’s track record for *other* projects? For an investor, RERA compliance and clear legal status are non-negotiable. Any hidden issues I should be aware of? I work in real estate but buying for myself is different; I need honest opinions.
