Selling big house, buying small - this tax maze is tiring

Section 54EC bonds mein capital gains tax save karna kitna practical hai? My kids are settled abroad now, so we're selling our big Noida house. Looking for a manageable 2BHK somewhere like Sector 150, maybe a Godrej project. Everyone says 'tax benefits le lo', but the rules seem like a maze. Is it worth the headache, ya just pay the tax? Any real experience with this in Greater Noida?
