I could be wrong, but IIRC what you're smelling is a sulfur additive which is supposed to improve lubrication under high pressure or something like that. Park Cutting Oil also smells a little like that, BTW. It doesn't mean they're all the same stuff though (though I wouldn't be surprised if the cutting oil fared well as a chain lube).

Gear oil includes some additives that helps in high pressure applications. After reading all the opinions and "science" behind chain lubes, I think I will go back to my old diy mix. I didn't use any oil lubes on my first "modern" chain in 3x7, and it lasted the same amount of miles looking and working good, the same way as other chains that received a lot of lube love.
It's one of a very few topics that gets so many completely different opinions...

I like the Chain-L.
It's thick, and so is the factory lube that comes on the chain, it's like grease.
Some of these companies use the "fast food" way of marketing. They come up with a different lube for different weather or terrain... just to get you back in the store to buy something new.
So to answer the OP's question, use thick lube.
Beside, the smell of the Chain-L takes me back when I used gear oil...it's like coming home!

The smell of Dumonde is similar to when you disturb a large red ant pile... like pheromones.

I've never bent over to smell an ant hill.
What is that like?

You've never played with ants? Lucky you!
