Here, I found this information online:
“There are pros and cons to both steel winch cable and synthetic winch rope, and which one is best for you depends on your specific needs and preferences. Steel winch cable is generally more durable and has a higher breaking strength than synthetic winch rope, making it a good choice for heavy-duty applications where the winch is frequently used or where the load is very heavy. However, steel cable can also rust, kink, and fray, which can lead to dangerous situations if the cable breaks or becomes damaged during use.
On the other hand, synthetic winch rope is lighter, easier to handle, and less likely to cause injury if it snaps under tension. Synthetic rope is also more flexible and easier to store, which can be an advantage if you have limited space. However, synthetic rope is not as strong as steel cable and can wear out faster if it is subjected to harsh conditions or if it is frequently used. Ultimately, both steel winch cable and synthetic winch rope have their advantages and disadvantages, and the choice between the two will depend on your specific needs and circumstances. If you are unsure which option is best for you, it is recommended to consult with a professional or an experienced winch user.”
