I've been running wikis the last 20 years, but I too use static files for note taking, a wiki is not for everything IMHO. Zettelkasten just feel like a low tech wiki to me. Is it really that great or is it just the simplicity that makes you a convert?
I admittedly have not been using it long enough for it to come into its own (when the connections should start to do more heavy lifting). But my impression so far is that the "low tech wiki" description is essentially accurate, although since I keep all my files in one folder, I find it easier to get an overview of what topics I've already covered. I guess there's probably a page for this in most wiki systems as well, but I'm not a wiki power-user.
The reason I'm a convert is that it seems like the best of both worlds between raw note-taking and a wiki. The advantage over raw note-taking is the links that enable you to "crawl" its entirety. The advantage over a wiki is that it's tech-agnostic and you can do it however works best for you.
On the other hand, a wiki may be better for someone who wanted to embed media in their notes (such as audio recordings).
