If you've been around woodworking for very long, you are familiar with the Kreg Jig system. It allows you to quickly and easily join wood together without gluing or nailing by creating a perfect pocket hole. It creates a strong joint with Kreg's self-tapping wood screws.
I use the Kreg Jig for various joints, primarily when I want to join two pieces together where the pocket holes are hidden. For visible joints, I tend to nail them together with a finish nail gun. I just don't want to use the plugs and the nail gun is much faster. However, the pocket-hole joinery is much stronger and it can be used on edge-to-edge butt joints (e.g., face frame), whereas you cannot use a nail gun for edge-to-edge joints.
