The marlinspike hitch is the best bang-for-your-buck. The author of this video shows it in quite a few of his other videos. Depending on what you do with the tag end, you can quickly collapse it into a bowline for a fixed loop (and subsequently apply any bowline finishing you might like), or you can end up with an Ashley stopper (which provides triple the diameter of the rope, so is an excellent stopper). Using it actually as a marlinspike hitch gives you a really nice handle to pull in tension on a trucker’s hitch. The knot also does not jam, so you can easily pull it out just by completely tightening it. This same property makes it an excellent choice for the loop in a trucker’s hitch… provided you get the directionality right so the force of pulling in tension counteracts its desire to collapse. When you’re done, the loop can just collapse out when you untie it—no dealing with a jammed alpine butterfly.
