Button vs Hamilton? They were at different points in their careers. Hamilton convincingly out qualified Button and scored 2 more race wins. Button scored more points. I have never read anywhere that Button admits Hamilton was better than him! Car dominance is a very real point. No car has been as dominant as the current Merceedes. Not even the Red Bull. That Vettel has not been able to continue to be in the masterclass since leaving RB -or even when he had a much stronger challenger in Ricciardo- speaks to the dominance of the car. It raises the same questions about the dominance of the Mercedes too. The brilliant/dominant RB perhaps allowed to win Vettel four championships... In real terms comparing drivers against each other is difficult. Is it actual points, race wins, qualifying times, lap records, luck and the cars they were given or a mixture of all that we each form our own opinion? Personally I think Hamilton is a very good driver, definitely one of the best in recent years. But I've said that before.
