Sorry, got my names all mixed up there, but you get the idea. The ones in the first link I use to hang a screen on the wall, or a heavy picture. The Togglers I use when I am hanging a TV.
Keep in mind, the drywall itself is still a possible failing point, and I've done a articulating mount once, and only once, and found the drywall started to have some issues, so I went to a tilting mount instead. The toggler didn't come out of the wall, but it started pulling the entire drywall sheet off the wall! So, keep it tight to the wall and don't mess around with the tilt angle by pulling on the TV a bunch.
