Try some professional-geared products and you'll have a better comparison. Even some detail sprays offer protection that is comparable to spray waxes. When you look at the time needed to apply the spray wax, you can expand your options to detail sprays, waxes, and even sealants that can be applied in a similar time frame.
I would recommend Optimum Car Wax
[their wax option comes in a spray, not a paste]. You spray it on and immediately remove it, there is no need to allow it to dry, cure, haze, flash, etc. I guarantee that it will be one of the slickest spray waxes you could ever use, and it lasts months, not weeks like a traditional spray wax.
With that said, there are also spray sealants like Chemical Guys Hybrid V7
And even a rinseless wash can offer protection like Optimum No Rinse Wash and Wax
Don't just stick to over the counter options as higher quality products will last longer on your vehicle and the product will go further.
