I'm going to say IME anything that feels "slick" has silicones in it (regardless if it's called a sealant or a wax) and dust will tend to stick to it. This is just part of the equation though, as show type waxes are oil heavy, and dust will stick to that as well as Todd stated.
My experience tells me none of this is really clinically significant. Dust/pollen is go to be more of a byproduct of your environment and/ or the season - not the LSP you use (coatings may be excluded).
So, just use what you like and wait for pollen season to end. Dust on the other hand - don't think that ever ends. If it's just "dust" and the car is clean, blowing the car down with a Metro Sidekick seems to remove a lot of it. Constant wiping down of a dry car with QD or waterless wash is a way to induce marring IME - especially noticeable on a black/dark car. So, wash more frequently.
