This is probably because when another chapter is fighting alongside the wolves, they see the wolves do things they would not do. It varies from chapter to chapter, but think of how appalled the thousand sons were when the wolves burned libraries. Sons of Horus even state that they don't enjoy the Space Wolves company. Never is it explicitly stated that the Space Wolves are the best, it is just explained that they are a chapter that others would rather not fight against, or with, savages, and deadly.
As it has been mentioned previously in this thread, the wolves do not have the hesitation to kill. Think of how many times the good guy has died in the fluff because they hesitated killing the bad guy. Something along the lines of, "You were my battle brother, I cannot finished you off." Right before they get stabbed in the chest or something. An executioner does not think like that before flipping the switch or swinging the axe. They don't ask questions, they just keep chopping off heads until told to stop.
So when the Big E wants something done with no questions asked, and no other chapters popping in to say, "Oh hey there, we were passing through and saw you were taking a planet, want some help?" he calls the wolves. Thanks to reputation, none of the other chapters have any interest in being friends with the Space Wolves.
So Wolves don't really have friends, don't ask questions, and have some of the better infantry (if comparing codex, remove anything related to the HH, blood angels dont have red thirst and chaos marines did not have chaos power and all whatnots and hoo haw) Grey Hunters at the time, were pretty beastly, other armies have since grown to have equally beastly troops. Wolves also have some unusually good scouts and Long Fangs are awesome.
It is a combination of these things that makes the wolves good for the job of executioner. Not that they are the best of the best of the best. They simply have the traits for the job. Remember how pissed everyone was that they did not get chosen to be warmaster? That is how Warseer acts about being the executioner.
