"Seamless" may be irrationally exuberant but it's better than the others _at scale_.
LibreOffice, etc. may see similar from the UI end but if you're scaling across multiple sites/archetypes/employee models/regulatory environments, -and- want access to a wide and deep pool of administrative labor, M365 is seamless by comparison.
