nothing, not one thing you have said is any benefit to me. I have multiple bank accounts. I am employed, the DTV allows me to do that job in Thailand. Never ever once have I had an enjoyable trip to immigration - I never have to go whilst I have the DTV . On non o you need 800,000 so what is your point?
So yes I have a much better option, I know it as I have had the other options.
DTV wins every time
One thing you didn't mention was the multiple entry, that alone saves 20,000 BT and no chance of visa getting cancelled because you forgot to get a re entry stamp
