Interesting development with Cosmic Spritz-only vs Cosmic Spritz with HG on top, particularly with beading (see below). Note that these observations were on a car that had been cleaned last on Thursday (2 and 4 days before my observations), but the car looks clean with a slight layer of grass pollen building up over time.
As far as looks, the HG has a “brighter” shine in sunlight. I was almost blinded Saturday when staring at the hood under the sun, but the driver side with HG blinded me a little more. The sun was overhead and was shining down equally across the entire hood. Maaaybe slightly more flake pop on the HG side too, but so hard to tell when they are both sparkling and I’m half-blinded. I will compare again in different lighting (less sun or sun not directly overhead). Pictures don’t do any justice so not including any.
Now, as far as beading: it rained last night, I didn’t get to observe while rain was falling, but got to observe this morning with drops all over. Passenger side is Cosmic Spritz only. Driver side topped with HG:

I then took a 10 minute ride down backroads, 35-40mph max and watched as the HG side drops flew off the car at rapid pace. The Cosmic Spritz-only side drops still moved, but not nearly as fast. Here’s the hood while in the car:

Drivers side nearly dry. Passenger side still has very small beads remaining. Here’s one more pic after the 10 minute ride was complete:

Same results as the description above.
In summary, I expected HG to impede the beading of the amazing Cosmic Spritz. The result were the opposite. HG improved the self-cleaning by a significant amount! The car was not just cleaned and did have the slight bit of grass pollen and had been driven for 4 days before this observation, but regardless the results surprised me. HG the self-cleaning winner... when used on top of Cosmic Spritz.
