Vietnamese is easier to learn, and computer input and handwriting are easier. Vietnam's economy is now in a state of rapid development, and many commercial projects are occupied. Perhaps the development opportunities are not as good as those in Myanmar, where the economy has just started. Many countries have almost no computer input method in Burmese, and I don't know if there is one in Myanmar. Handwriting is very troublesome, but it is easy to write Burmese without input method, and there are more opportunities for development in Myanmar.
I suggest that the landlord choose Burmese, but Vietnamese and Burmese have their own advantages and disadvantages.
