From past threads/topics on this subject, you'll get a range of comments from every one is great to simply go without.
Personally, I'm using a DIY mesh tarp cover stretched across the front end of our Wrangler from just above the tow bar knuckles to half way up the hood, held in place by bungee cords. I hope it will protect the nose and lights from light to medium weight road debris. It has not been road tested under live towing conditions, but I expect it to be functionally somewhere in between Protect a Tow, and nothing. It cost about C$50 to create. :B
