Leak down = engine pressure loss test - over time. It is more accurate than a simple compression test, but I've always found that a compression test (done correctly) will give you the correct results and that a leakdown will just confirm it more ecurately.
Plus a compression test is a hell of a lot easier than a leakdown - especially on a mid engine flat six configuration.....
