We actually switched our entire engineering team to Excalidraw from draw.io and Miro and we love it. There is something freeing about it.
I noticed in draw.io people were spending lots of time aligning elements and trying to beautify the skematic which I considered unnecessary. I wanted something that resembles the whiteboard back when we were in the office.
The sketchy feel of excalidraw does something to people. The first version is usually good enough. And we never had an issue not understanding our own diagrams when we came back to them later.
