Doesn't the question ask how a Borg Drone and Jem'Hadar fighter would do in hand- to-hand combat? I'm not sure how the comparison of the two fleets came into play.
Anyway, I think the Jem'Hadar is in trouble, if weapons are not allowed. Remember, in Best of Both Worlds, Worf was thrown to the ground quite easily by a drone. The Borg Drone is certainly stronger, and though it's slower, it should win. It's also more durable than the Jem'Hadar.
Locutus was bringing Worf to his knees before Data made the save, also. Borg Drones are very powerful.
