I did not mean to imply that using DStudio (or any such tool) is perfect. There are no (zero) dialogs that I have created in DStudio that don't need a bit of tweaking to finally end up pleasing me; I almost always have to change the ID order to match my own personal ID numbering scheme, and there are usually pixel changes I have to make, again, to please my exacting standards for "production dialogs" (I use Magnifier to see the actual pixels and get everything lined up exactly as I want it). Then again, I use only one scripted dialog regularly in "my collection of scripts" (rather than "my script"): my MP3 player.
However, DStudio "gets me in the ballpark" far faster than coding the entire dialog table from scratch. Then it's just a matter of tweaking after that (which is where the real fun lies - not in getting them close enough to tweak!).
