My [very biased] $0.02:

If you need only coverage on the most recent git diff / patch + looking at the repo level coverage on the head of a branch, both do a reasonable job.

Codecov's focus on code coverage largely branches off on:

-- Tracking the git tree (comparing base to head of a PR) --> e.g., how much did test coverage change on this branch / PR

-- Supporting monorepos: Demarcating by test type ("Flags") and team/module ("Components") so you can focus only what you care about vs. the full repo.

-- Supporting partial test runs: Codecov lets you run only some of your tests and still show accurate overall coverage data.
