It's a best-in-class real time collaboration board. It's also a decent general purpose diagramming tool, but if you're using it for creating software architecture diagrams or product flows, there are better tools for that.

Miro was always fine to use at work. It’s no Visio desktop or OmniGraffle but it wasn’t offensive and I only somewhat preferred LucidChart over it.

it was excellent at whiteboarding remotely.
