Traditional breeding yields crops with numerous unwanted and unidentified genes while genetic engineering only brings in the targeted genes.
Genetic engineering does however allow for the genes to come from extremely dissimilar sources though the designs prefer to avoid such extreme options when they can. As to viruses, all bets are off since we already know that viruses shuffle genes from all kinds of species whenever they damn well want to because they are viruses and don't give a damn. It's amazing how much horizontal gene transfer they are finding in nature.
By the way, in case you weren't aware, they've found a lot of dna in humans that they believe was put there by viruses.
I was aware but as the old saying goes:
To err is human, but to really foul things up you need a computer.
The same applies to traditional breeding vs GMOs. Genetic modification is a much more powerful tool than the various sources of random mutation. As such we're going to create new classes of risks that we don't understand yet. We don't exactly have the healthiest environment right now and farms aren't sealed labs, before we inject massive numbers of plants with several novel and powerful traits into an ecosystem we need to understand what the effects of those actions are.
