Answer 3

What joint to choose depends on the situation, the accuracy of your tools, and your skill level. There are pros and cons to miter joints as well as other types of joints depending on how they are used. For making rail and stile doors, a passing joint is easier to make tightly than a miter. For installing baseboard, outside corners should be miters to hide end grain and put the seam on the corner, but inside corners can use a passing joint, which is easier to make.
