David, I've only used the one I purchased from Amazon, but I've read where others are satisfied with the T Sportline product. I would test them both on a small area to see if you are satisfied. Depending on your level of perfection you may find one better than the other. I can't really tell a difference unless I get on the ground very, very close to the rim. There's plenty of tutorials on YouTube if you are interested to see how others have handled this--just search curb rash Tesla. Good luck.
