I would rather choose American variant of educational system. It made an impression to me, because all students study in the same way despite the “form of studying”. In the university or college you can choose subjects yourself, that gives you an undoubtful opportunity to study what you really need and want. Prestige of american education is one more thing that i want notice. After finishing American university or college you can without any difficulties get highly-paid job. Also i want to say few words about plagiarism in America: it is strictly prohibited and may lead to expulsion from university.
