Is going for the verification of answer sheets better or the?
Inspection includes verification also. As per ICAI's policy, If any candidate have applied for inspection of certified copies, then before providing the same they suo moto do verification of certified copy. If there is any chance of any mistake or error, they correct the same and update the result. In my opinion, you should go for inspection of certified copies. By doing this, you'll get to know about your weak points. And where are you doing mistakes. You can compare your answer with suggested answers given by icai. And point out the key areas on which you can put more efforts. So it's always beneficial to go for inspection.
