I certainly know what I am talking about, at the moment I have the possibility to get both, but because I am still working, for a part of the year in my hometown, and the other part of the year, DTV now is the right visa for me. When I stop working, non-o retirement might be the best one.
In the first place DTV is meant for digital nomads and remote workers, not for retirees to get this DTV with all kind of stupid tricks.
And indeed DTV is a bit cheaper in some situations, but the visa process is not really different.
When you want to stay whole year in Thailand you have to do a border bounce at least once a year, which is already a sign that you have the wrong visa. A border bounce is also costing money, so I am not sure it really is cheaper in the end.
When you don't work anymore, you have to apply for soft power, also costing money.
DTV is for people who don't wat to live the whole year in Thailand, but only longer periods of the year. There is a reason the stay is only 180 days and can only get extended once.
People should always look which visa is meant for which purpose, but for some reason there are a lot of stubborn visitors of Thailand who want to trick the visa and visa exemption system.
P.S. I did not say it might be an option in some cases, like people still working after they retire, but it normally is not the recommended option, and nothing in the post of topicstarter suggest that in this case DTV might be a good option.
