What do you all think—between South Korea and Taiwan, which stock market is more worth investing in?

If we set aside Samsung for South Korea and TSMC for Taiwan, although Taiwan’s stock market seems more open than South Korea’s, its industries are quite lopsided. Beyond semiconductors, the profit margins of Taiwanese companies are almost universally low. South Korea, on the other hand, seems more closed-off, but its industries are relatively more diversified, and their profit margins almost always outperform those of Taiwanese companies. Which of these two countries do you think is more worth investing in?
