I like that it allows me to see my prices compared against other sellers in our category - so if there's an opportunity where another seller might be better off than myself by changing the price range or amount they charge per unit sold, then I'm able to take advantage of that difference before anyone else does! It also makes sure there aren't any errors with listing rules (such as minimum inventory) which could otherwise result in losses due to selling below cost! Some things require manual intervention after setting them up correctly (ie some categories don't have auto reprice enabled). We've been using this since launch day when first set up and haven't had problems yet.
