I am a graphic designer (and no, I wouldn't use MS Paint) but I don't have a lot of coding experience (as you can tell by my questions) but I am learning WF-Sections and I do think it's pretty complicated. But I also think it's worth it if you are going to have a site that really relies on various kinds of articles.
And remember, the WF people are working on some much needed documentation for the module too. So in my opinion, it's a good module, that is only getting better.
Oh, and one of the most important things that XOOPS can do is incorporate a cross-platform wysiwyg editor into the next version in my opinion.
