Fusso Coat 99 12M (hard wax) or Fusso Coat 99 F7 (liquid wax)

Hello, I plan to use one of the two products mentioned above for the first time. I tend to liquid wax of the Fusso 99, simply because it is probably faster and more stress-free to apply than the hard wax. Does anyone have experience of you with the liquid wax of the Fusso compared to the hard wax and can tell me something about it? I am especially interested in possible differences in result and durability.
