Question: What is the Best timing chain setup LA or Magnum

I have an LA318 that has a tried timing chain in need of replacing. So now I'm looking for the best setup. I like the idea of the magnum setup with the chain guide, but I also like the like the idea of the double roller setup. But I don't know?
What's the best setup?

Chain guide? No such thing or reason to have a “Chain guide.”

I like the double roller with the Magnum timing chain tensioner.
