Wow. Downvotes. Sure. Here are just a few off the top of my head.
1. Excalidraw doesn't allow you to quickly connect components.
2. It doesn't _always_ allow you to double-click on a component and add a title to it, so you end up using a Text component, which is obviously not what you want because two of the components are not linked.
3. You can't title links/arrows between components.
4. It's cool that they have a components library, but it's barely useful (right now), so I would either make it really good or drop entirely.
