In many cases, a high quality (and there are some) Taiwanese or Korean part can be better than a cheap british, european, american part in both fit and quality. Problem is, it's hard to tell, and quality control, while abyssimal in many american plants, is even worse in many asian plants. In the same batch of parts from a given supplier, you can get both parts that fit perfectly and those that require significant adjustment. Makes no never-mind WHAT country they come from.
