Yes, it's a great default adjustable knot! The other one I think is worth knowing is the "adjustable grip hitch", which is like the midshipman's but the half-hitch goes on the other side of the turns. This latter one seems to hold a lot tighter once dressed, even in relatively slippy rope, but unlike the midshipman's it can't easily be tied under load.

The adjustable grip hitch is great but the Blake’s hitch is almost magic and my favorite knot right now.
