I have been using Boltor now for a really, really long time. A clan member insists that the Gorgon is better. I got the Gorgon up to level 30 some time ago, potatoed it, and was underwhelmed. I think it was just because it seemed to lack longevity in it being an ammo fountain. It could be that I didn't have a good mod build with it. It could be that I was not giving it a fair shake.
In the end, I have a question to others who have played with both primaries : Which do you prefer?
Bonus Question : Is there a primary superior to Gorgon and Boltor?
