Which is better to travel to in Vietnam, Nha Trang, Sabah or Thailand?

I have been to Nha Trang, Sabah, and Chiang Mai, Thailand. I went to Nha Trang during the National Day holiday last year. With a low consumption level, Bamboo Island is worth a visit, mainly for its amusement parks and water recreation projects. The four-island tour is of little significance, but the song and dance performance is somewhat interesting. The remaining scenic spots near the city can be visited in one day, and you can take a mud bath. For food, you can experience Vietnamese cuisine.
