Capital gains tax: Any better options than 54EC?

The tax implications of selling our property and buying another are quite intricate, especially concerning capital gains. Kids have moved out, so we don't need such a big place anymore. We're seeking a manageable 2BHK in Indirapuram or Vasundhara. Our current house resale value is good, around ₹1.5 Cr. Capital gains calculations feel complex. We're considering a compact flat, perhaps from Gaurs or ATS, around ₹70-80L. Any advice on Section 54EC bonds or alternative ways to mitigate LTCG? Is it advisable to lock funds in 54EC for the long term, ya koi better options hain?
