At work, I am required to use SPSS modeler which has visual programming model, and I mainly dislike it for the reason of not having a way to easily diff and find out what has changed.

That aside, I think most of us actually code in visual programming style, but all the "visuals" are constructed in our head on the fly as we read the code text. So how good you are at coding maybe a function of how well you can represent these structures and how long you can maintain them in your head. Maybe an external tool that does it for us produces a representation doesn't mesh well with the internal representation for programmers experienced in text based programming.
