I would argue 10/10 scores and 5/5 stars aren't the same. Even if you can have halves in the 5/5 score, like in Hummingbird's case, which would make it technically identical to 10/10.
For example, 3/5 is a higher score than 6/10. This might sound weird, but it is as far as I know psychological. It depends on how you process the meaning of the score in your head. Especially since 5/5 scores are often represented visually much more than 10/10 scores, which are more often than not entirely numerical.
