I've always liked the half-crab/scorpion deathlock.
There have been some guys over the years who've come up with some very clever ways of getting into the move.
Bret could seemingly hit it from any position, and Lance Storm often prefaced it with a beautiful roll-through.
Ironically, I cared for Sting's version the least.
The way he put it on made it appear as though the only reason he could hook it was because his opponent let him.
While slightly different from a traditional SDL, I also liked Dean Malenko's cloverleaf variation - particularly the speed with which he could apply the hold.
