I’ve heard lots of arguments on this topic. I always thought that the screw types are the most reliable, but I’ve heard lots of people complain about the noise, recommending belt types instead. I’ve always seen the chain types as “cheapies.”
Truthfully, I’m hoping some of you can share your personal experiences and wisdom to clue us in. Which one is best? Let us know in comments.
