I'm with you here, and I would have written the same thing if you had not done it already.
However, having stated this point, we can elaborate further on it and see that's not as true in Star Trek as it would be in a real universe. Star Trek aliens are always kind of personfications of human charactaristics, singled out and exaggregated so we can learn something about ourselfes, so they are somewhat stereotyped by nature.
Star Trek tells us Jem'Hadar or Klingons are "all" natural born warriors.
In this sense, I would vote Jem'Hadar, but first and foremost, I would, like you tend to break it down to the individuum.
