Hey Joel,
Like Orin mentioned, the jelly w/ added protein is mainly used for Stags; usually for female Dorcus stags who need protein to induce laying. I've fed it to ground beetles, velvet ants and millipedes and it works well.
There are many other fruit/sugar jellies (banana, syrup, melon) that are geared more toward Dynastids or Cetonids who don't really need protein as adults. Other than that there are so many brands and flavors that is gets scary. I think the diversity can be compared to sports/energy drinks here: every one has something that the others don't that is supposed to make it better. Either way though (protein or not) jelly is so much easier and better than fruit.
