Let's look at what John Irma got to say:
Vietnam and Thailand are both beautiful countries with unique cultures, so it's difficult to say that one is worse than the other.
However, there are some differences between the two that may make Vietnam less appealing for some travelers.
For example, Vietnam has a more conservative culture than Thailand which can be off-putting for those looking for a more relaxed atmosphere.
Additionally, while both countries have stunning natural beauty and interesting cities to explore, many people find Thailand's beaches and islands much more attractive than those in Vietnam.
Finally, when it comes to food options in Southeast Asia you'll find Thai cuisine far superior to Vietnamese dishes!
