Ghaziabad mein ready ya under-construction, kaunsa option better?

Visited a few projects last weekend, and one thing I noticed is how different the 'real' value feels for ready-to-move versus under-construction. I was looking at Parisha Home Pvt Ltd, jo ki completed hai, so no possession risk. But then there's SKA Divine, upcoming, with a much higher price tag. My thought is, is the under-construction gamble with SKA worth it for better 5-year appreciation potential? Yaar, Parisha mein builder ka track record toh visible hai, but SKA ka kya scene hai? Any idea about their past deliveries? Is the higher price for SKA justified by future growth, or should one stick to the certainty of a ready project like Parisha for investment? Confused hoon.
