The ease of use is one thing that I love about flash node they make it very simple to set up your integration with any platform or software you are already working in so there's no learning curve at all! We have been using them since we started our startup but now as an established enterprise marketer their support team has gotten even better which helps us out when issues do come along from time-to.- They can be expensive depending upon how many APIs/integration points exist within each application (which seems normal). If this will solve most problems then yes definitely go ahead otherwise find another option if price isn't important - maybe try integrating through Zapier? Integration between Salesforce Marketing Cloud + HubSpot = amazing results.
