The best tire dressing is determined by what the owner like best! Once applied, some last longer than others but, none last as long as I would like. If you like a greasy/wet looking tire, there are plenty of products for that!
I have used many tire care products and, personaly I don't like the tire to look too greasy/shiny. But, I do like the look of a tire that is "DARKER BLACK" but clean & dryer looking, due to a tire care product.
I usually dilute my tire care products by wetting my applicators, as to cut down on the shine of a tire just treated.
Also, I use one product for all(tires, interiors, moldings, rubber etc.) In other words, I don't buy several products for each surface as the products are marketed. I just use one(which ever I buy on sale, no brand in particular).
Although I must say, for interiors I actually like leather cleaner/conditioner even for my vehicles w/o leather. I like it better on the dash, consol, door panels etc. It gives me the look that I like for my interiors(the whole interior!)
So, I guess that I use 2 products!
...But, I'll often use the tire care product elsewhere on the vehicle(wheel wells, mud guards, under hood).
