Best president of any country? That would be Ferdinand Marcos of the Philippines. Yes, he was a dictator to some extent, but who could hate a guy who chose a wife who had a shoe fetish like Imelda Marcos, you cannot hate, you can only say he was the best ever.
Look at what the president accomplished in historical perspective. If you do your research I think you will agree that the greatest presidents were: George Washington, Abraham Lincoln, Teddy Roosevelt, and Ronald Reagan. History will judge the others.
