People often joke that "America has the worst form of government on the planet except for all the others." It ain't perfect.
And it certainly isn't better than all the others. It has strengths and weaknesses in comparison to other large nation-states, and those are a matter of taste. There are small nation-states which have systems which are vastly preferable to the U.S. system, in my opinion, but they are generally special cases. Iceland is not too bad. Norway is fairly tolerable. I could almost stand Scotland. Singapore is rather decent. Chile, quite nice. Conceivably Paraguay. But then I've not lived there long enough to see the worst aspects, to judge how deeply they disturb me.
Compared to the Parliamentary System in Canada I have always thought that the Presidential System in the USA and many other countries around the world is a breath of fresh air.
Imagine having a system where you vote for someone who ends up voting for the leader of your country...that's basically how it works in Canada. In Canada, our leader shows up for work in the House of Commons (Canada's form of the House of Representatives) every day...the Senate and the Governor General (Canada's form of a President) are just figureheads.
