Adding some nuance here — it really depends on the region and data type you need. From our experience:
ZoomInfo tends to have stronger data in the US, especially for direct dials and work emails at mid-to-large companies.
Apollo performs better in other regions (LATAM, parts of Europe) where ZoomInfo's coverage gets thinner, and their LinkedIn-based data is often more up to date for job titles and company changes.
If you're primarily prospecting in the US, ZoomInfo is probably the stronger choice. If your ICP spans multiple geographies, Apollo's coverage might actually be more consistent overall.
