I think Salesforce has so much functionality that it makes it difficult in terms of overall usability. Once you can figure it out, it's a 10/10, it's just getting there. If you're willing to do the work to figure it out then you're golden. For what it's worth, I don't know if you're going to find something with this level of functionality that's easier to figure out.
