IK is far better than other two which doesn't mean that he is an angel who hasn't done anything wrong. He has not been tested yet as a Prime Minister so nobody's sure what he's gonna be once he gets power. He does have some issues like party foreign funding, offshore company's tax evasion and now the bani gala's one. His party member Jahangir Tareen got his loans written-off in the past. He's becoming controversial as he spends more time in the politics. He wasn't as controversial as he is now when he stepped into the politics but this is how people change or politics change people.
