DTV you need to visit immigration at day 90 of each stay, unless you travel every 90 days.
So when you not want to leave the country every 90 days, with DTV you visit immigration more often than with non-o.
With DTV you might keep your current bank accounts, but there is also a risk they have to be closed.
On non-o you don't need 800K when you have income of 65K each month.
The 20,000 for re-entry permits is only when you travel 20 times in and out the country, which is not something the average retiree does, and then you could better buy a mult re entry permit, would cost you 19,000.
And just like I said before, in some cases DTV might have some advantages in mainly edge cases, but generally spoken non-o is the better visa, in fact the only disadvantage is you have to extend it always in country around the same time of year, so when you travel a lot and are longer times away DTV might be better.
