It depends on which Hubspot plan you are on, but generally:
Airboxr is more flexible (as much as a spreadsheet) and can help you combine data from multiple sources. Oftentimes, you will need to combine data from Hubspot (e.g., number of leads added on a particular day) and Google Analytics (e.g., traffic of users on that data).
If you are on the Hubspot Marketing Hub plan, Airboxr can help you pull statistics for open-rates, click-rates etc into any spreadsheet for your reporting or decision-making.
