If you're reading this on the Athena website, you might assume we'll tell you the enhancement approach is universally better. We won't. Complete intranet products have real strengths. Powell, LiveTiles, and intranet.ai have invested years into packaged experiences that drop into a tenant and work immediately. For an HR director who wants an intranet live next month, with no SharePoint admin time, and is comfortable with the vendor's design choices, those products are genuinely faster and lower-friction than the enhancement path.
The enhancement approach requires somebody, an admin, an MSP, or a designer, to actually design the intranet. If that capability doesn't exist in your organisation and you don't want to develop it, an enhancement tool will sit underused, and a complete intranet product is the better call.
The architecture decision is genuinely a values decision: control vs convenience, customisation vs configuration, long-term independence vs short-term speed. Both answers are defensible.
