My experience has been to do a compression test first. One "dry" the other "wet" if you have a low reading. You then add some engine oil to the cylinder, and re run the test. If the compression numbers come up, then the rings are suspect. If the numbers do not come up, some thing else is wrong, like burned or poorly adjusted valves, bad head gasket, etc., so then you do the leak down test.
