Saber is definitely better but it's too much to expect that he is a clean person as after all he is a politician in Bangladesh. But he isn't someone who will only take, he will also try to give back. With Papon and the others its only taking. Saber is a visionary and will improve the BCB for sure.
That's the only difference. All delhi politicians are crooks, sOme are lesser crooks than others. So for us Saber is the best choice as falls in the less corrupted category. I hope he gets the post but I doubt Papon will let him.
