Zapier addon substitute of Salesforce/Hubspot addons

For sending lead generated through WPForms to Salesforce, there are two ways. Either use Salesforce addon or Zapier addon. Again for sending lead generated through WPForms to Hubspot, either use Hubspot addon or Zapier addon. Or why not instead of using Salesforce addon and Hubspot addon, use Zapier addon if one strives to integrate WPForms with both Salesforce and Hubspot.

Curious to know if I am correct in my above understanding.
