Pricing Hub allows us to see what products are performing well, where we need improvement, but also how much impact any changes have had - they provide all this data at your fingertips for you! I would say that one of my favourite things about them is the ability to make quick adjustments as needed without having someone else involved every time you want to do so.
One thing i dislike is there's still no integration with other platforms like Salesforce or Google Analytics- maybe someday? The support team has been incredible when needing help. They've taken over from another vendor and improved upon everything, especially reporting options/data analysis capabilities.
