Liberty Mutual vs Mercury: which is better for car insurance in 2026?
Across our six scoring categories, Liberty Mutual comes out ahead in 2, Mercury in 0, with 4 too close to call. There is no overall score to compare, though: Liberty Mutual does not publish enough of the underlying data to earn one, and we would rather leave it blank than build a number out of the two or three figures that happen to exist. Mercury is the better-documented of the two, which is not the same as being the better insurer for you. Judge these two on the categories where both have real figures — and on what they actually quote you.
