When Google’s server is the better choice
You want answers about one GA4 property today, you are comfortable with Python and a Google Cloud project, and each question stands on its own. It is free and available now, which OneLap is not.
When OneLap fits
A team or an agency wants GA4 next to its other sources, reports where every claim cites a source, and a record of what was decided and by whom. The data, the history and the approvals stay in OneLap, so you can change the agent and keep them.
