I like plantuml as well. I use it with all my preferences saved in vscode's user snippets. draw.io is seems to be preferred option at work as draw.io diagrams can be embedded into documentation (e.g., confluence) and are editable in future.
Actually, PlantUML is available as a plugin on Confluence. I am currently using the plugin at work. Since PlantUML supports converting a diagram to a SVG file, it should be embedable with other platforms too.
The good thing about PlantUML is that it's a text-based diagram tool. You can put the text in version control, like Git so you will know the revision history.
