I am sure there are benefits from other visas for other people- for my situation, the DTV is really how I “use” Thailand and happen to be married to a woman who is Thai.
To put the question a different way …
if I have had a Non O based on marriage, will it negatively affect my chances of obtaining a DTV ?
my wife and I travel together and have residency in other countries also .. we are really mostly retired and enjoying life in several countries. When we are in Thailand, she can work if she wants to and I really have no need to.
