Just wanted to add:

1. Al-Muwatta is considered to be more Sahih than both al-Bukhari and al-Muslim in certain regards in spite of having mursal narrations due to the shortness in its chains of narrations and also because those mursal narrations were later confirmed to be sahih by subsequent scholars, increasing their stature.

2. There were many scholars of hadeeth in the past that held this opinion, even after the compilations by Bukhari and Muslim.

3. There are living scholars today who hold the opinion that al-Muwatta is more sahih then the sahihayn, and these scholars are not even Maliki (they're Deobandi).
