I really like grab for this reason. I have a friend who will think an Uber driver should get a 3/5 stars for a ride that was perfect fine. If you give a non-perfect rating in grab, it asks for a specific reason why, giving you a dialog with common reasons why. If you give a low enough rating, grab will reach out to you to understand what happened during the ride and to try to make things right.
