I tried it for a project and I was pleased with what I could do with it (links to other inner sections, web formatting, etc). However, i couldnt maintain this approach for new projects and daily notes, so i switched to Docsify and markdown a month ago. Docsify needs plugins to accomplish most built-in TiddlyWiki stuff (search, last updated subtitle, etc) and basically forces you to script your way to make a document structure and a working sidebar, but at least I find it less platform-dependent and more customizable.
