@Tom-Capper The integration is everything because it allows us (agencies) to have all the high-level metrics, at-a-glance on one report. I can definitely get the acquisition info from GA, but to have it on the report that we send to the client, makes the Moz report a one-stop shop experience. That's what sets Moz apart from Ahrefs and SEM Rush, etc. Did this answer the question?
Speaking of which: It would be amazing if we could have "seats" that were limited to specific campaigns and read-only. This would allow agencies to give their clients a login where they can see everything we see, but not change anything. In fact, this would eliminate the need for the reports, which we send them on a monthly basis. This would raise the agency's service value immensely, and therefore...Moz's
As for Search Console, it shows keywords that are no on the Moz Opportunities list because it shows keywords that are locally ranked high, and those that are ranked way down in position, which is helpful, because if a high CTR keyword is ranking in position 89, we can work on that to bring it up.
