Kind of like mb v.s. bmw. What ever won you own; you think its the best.
Overall they are amazing products but just like our cars you are also buying the name.
Swissvax is known for darker color cars and waterbeading.
Zymol is more of your any applaction type of product.
Personal its hard to beat Zymol Vintage Glaze just for the fact that it is lifetime free refills when you are talking about spending $1,000usd on wax. Plus it would look cool in your wine celler or on your desk!
I personaly like both the same, and when you use them on different cars you find what product works best for a certain color or clear coat.
