I made my durge a Tiefling sword Bard. It's worked great so far. Expertise in CHA skills is a hell of a tool. I made her look like Alfira. I think I stated that playthrough with the idea that Durge was actually a changeling like Orin, (but no mods, so i was using the shapeshifter hat) but I sort of dropped that idea part way into the run. I had a second Durge playthough where i was a Dragonborn vengence pally and planning to do a resist run. It took a while sorting through the Dragonborn skins, but I found one that basically looks like spilled petrol. She's beautiful, maybe i'll finish that run someday.
My reasoning is that I wanted a character who was either intelligent, or at least charismatic enough to seem intelligent. While the idea of the dumb brute Durge who knows nothing but murder, blood, eat roast dwarf and fuck corpse, has a certain appeal, looking at the canon information about durge's past, they seemed intelligent enough to come up with a scheme, and personable enough to get others enthusiastic about said scheme.
Maybe it was just my perspective, but it seemed like Durge had something about them that attracted people (god mojo maybe), they basically seduced an whole elder brain, and there are the implications about the nature of durge and Gortash's relationship pre-lobotomy. (also KRESSA fucking BONEDAUGHTER). The only one that seemed immune to their charm was Orin, and possibly Ketheric, who gave less than two shits when you walked back in the door after he spent weeks hiding you under moonrise and lying to Gortash about your death.
So I gravitated to classes like Bard and Paladin, classes that probably have decent CHA, and with varying abilities to fight.
