Rajkot property owners: Capital gains pe advice?

150 Feet Ring Road pe 3BHK dekh raha hoon, upgrading from my Nana Mava 2BHK. Already have a home loan. Selling my current flat means capital gains tax. Section 54EC worth it hai kya? Balaji Group jaise builders ke projects mein tax benefits hain? Is the premium for a bigger home really worth the hassle?
