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