I'm a fan of pre-commit/push hooks, but they have to be fast. At <dayjob> our suite of pre-commit hooks are <50ms and pre-push hooks are <5s. They get regularly reviewed for performance, and if anything can't be made faster, slow pre-commit hooks will get ejected to pre-push, and slow pre-push hooks will get ejected to the regular CI suite.
