Trump vs. Hillary

If Trump wins, there is as if a president (I do not say good or bad); If Hillary wins, there is as if no president (her decisions and her conflicting mind are always based on people's polls).

Which is better? I care not much of American Presidency since I learned of their "Manifest Destiny" which robbed half of Mexican land since the early years. But I will probably play a shrewd & strategic role in all of this.
