Why do people prefer to go to Thailand instead of Vietnam?

As both Southeast Asian tourist destinations, why do people prefer to go to Thailand and rarely visit Vietnam? From personal experience, the tourism experiences in these two countries are really different. No input provided. Natural scenery: Thailand has extremely rich natural scenery, many of which can be remembered by everyone, such as Phuket Island, Pattaya, Bangkok, Chiang Mai, Koh Samui, Zheng Wang Temple, etc. In addition to these, small and niche tourist attractions such as Chiang Khan and Elephant Island are also very worth visiting. The tourism methods are diversified and can meet the needs of different people. Compared to that, there are relatively few well-known tourist attractions in Vietnam. Tourism environment: Vietnam started and developed its tourism industry later than Thailand, and the overall industry is not as well-developed as Thailand's, so both the infrastructure and tourism environment, including shopping places, are not as abundant as Thailand's. I have been to Thailand 6 times and Vietnam twice. Overall, Thailand's city streets are cleaner and the cultural environment is better. Thai people are also more friendly and hospitable. My most memorable experience was riding a motorcycle in Thailand alongside cars, even during rush hour, everything was orderly and there was no honking, which I found quite impressive. Consumer level: The cost of living in Thailand is lower than in Vietnam, and it is also safer. Basically, a person can spend only a few thousand yuan to travel to Thailand for a week. However, there are too many things to buy, such as local jewelry and bags, which cost only tens of yuan. I haven't seen any sky-high prices for souvenirs. Especially, many floating markets are a shopping paradise for women. Speaking of shopping paradise for women, Vietnam is even rarer. Language environment: There are many people who speak Chinese in Thailand, and learning Chinese is very common in Thailand. Relatively speaking, Chinese people will have fewer language communication barriers when they go there. But if you travel freely in Vietnam, language communication will be very difficult. Movie promotion: People love Thailand not only because of their personal experiences, but also because of the recent movie promotions that reflect the country's good environment. There are more movies that showcase this in Thailand, especially some public service advertisements that are very touching. However, Vietnam has done very little in this regard. The above are the reasons why people like to go to Thailand but not Vietnam. What do you think?
