Auto Finesse Tough Coat Paint Sealant v. Sonax Polymer Net Shield question

I've read reviews on both of these products and am trying to decide which to get. Does anyone have experience with both and can offer a recommendation?

 

I prefer the Sonax used it many times and if you compare to power lock the only down side of Sonax takes longer to apply but it last long IMO. I have never used AF tough coat yet waiting till I run out of something first
