Why is phenolphthalein a better indicator than thymol blue?

Phenolphthalein is a better indicator than thymol blue for acid-base titrations because phenolphthalein changes color at a pH range of 8.2-10, which coincides with the endpoint of many acid-base reactions. Thymol blue, on the other hand, changes color at a pH range of 8.0-9.6, which may not be as precise for determining the endpoint.
