Yes, a presidential form has been shown over and over to be the best form of government that you can have, and there is not a way better. The parliament system is not all that bad, but it can not compare to the way that the system we have is.
Both systems have their advantages and disadvantages. The presidential system is better in my opinion because the people elect the President. The people do not get to elect the Prime Minister, as thet are appointed to the position. The parliamentary system is said to have a stronger party system, where the presidential system is weaker.
The parliamentary system is old, archaic and should be done away with in all parts of the world. The best way to go is a constitutional republic with checks and balances, where representatives are voted in. In the parliamentary system, the power is way too top heavy. Presidential politics are better.
No, a presidential form of government would not be better than the parliamentary system, because they both seem to end up in the same place. Both forms of government have a figure head for relationships with other countries. At the same time, they both are representative and engage a sizable number of legislators.
I personally disagree, A presidential system is a republic system of government where a head of government is also head of state and leads an executive branch that is separate from the legislative branch. The executive is elected and often titled "president" and is not responsible to the legislature and cannot, in normal circumstances, dismiss it.
