The only way to really know what's what however would be to do a side-by-side with both products and it's usually not reliable to go by your memory of how you think something felt in the past.
I don't ever get that deep into this myself. I trust the product to do what the manufacture says it will do and I get results that satisfy my car care goals. After I'm done waxing my car or a customer's car I usually clean up and move on to something else trusting that I've done my best regardless of any measurement in how the paint feels.
If you want more slickness, mist on some UQD and then feel the paint, maybe do a comparison with one section just the wax and another section with UQD
