The episode was pretty explicit that the Unas made the deal because they very much desired the naquada be used to fight the go'a'uld, not just because they were pitiful savages who couldn't feed themselves and needed to trade for food.
The episode didn't dwell, but the implication was not just that Daniel and company avoided a Custer's Last Stand scenario. Good for them personally, but it was also good for the Unas because the sequel would have been the annihilation of the Unas, just as the Sioux victory at Little Big Horn led to invasion by three US forces.
The three Unas episodes, The First Ones, Beast of Burden and Enemy Mine, are very strong drama, with quite interesting political overtones. (Other Unas appearances feature go'a'uld parasites, really.) Which, since SG1 is basically adventure/comedy as serious as National Treasure or the like, means they should be well worthy of comment.
But, practically no one else at this bbs would rate any as more than "serviceable," or "okay." Most people just call it boring, a meaningless term that serves to condemn when one either can't or won't articulate the reasons.
