I'm one of the GCP icon library people, but I'm not a collaboration tool expert. With that said, I have tons of tool opinions, as I'm sure many knowledge workers do. Here's my tips on when to use which tool.
#1 use a collaborative tool #2 use a collaborative tool that all your collaborators will use easily #3 use a collaborative tool that makes you very efficient
Lucidchart and other specialized tools will make you more efficient for diagramming because they have snap-to and other pro features, but they won't pass test #2 for some places. That's why we gave you both versions.
What version, templates and tools would you like us to add? Draw.io? Any others?
