How do you rate a book? Do you base your overall star rating on quaility or enjoyment or something else?

A year ago, I decided I wanted to be more consistent with my star ratings so I decided to use the following as my guide:

⭐️⭐️⭐️⭐️⭐️ Absolutely loved it/a favourite! ⭐️⭐️⭐️⭐️ Enjoyed; Would reread; would recommend ⭐️⭐️⭐️ Enjoyed; would recommend ; ⭐️⭐️ Didn't enjoy; would still recommend ⭐️ Didn't enjoy; would not recommend

But I'm not sure if I have it balanced well. I think maybe I should change it to:

⭐️⭐️⭐️⭐️⭐️ Really enjoyed; Would reread; Would recommend ⭐️⭐️⭐️⭐️ Enjoyed; Would recommend ⭐️⭐️⭐️ ⭐️⭐️ Didn't enjoy; would still recommend ⭐️ Didn't enjoy; would not recommend

But I'm not sure what to put at 3 stars.

Could I know other peoples star rating criteria, please?

Thank you!
