What I like most about Prisjakt is that they don't try to second guess what I want given a basic search phrase. Instead, Prisjakt gives me the categories to drill down into tables. Sortable and filterable tables with product name, price, rating, and category-specific columns (like storage size and $/GB for hard drives). The filters run DEEP. If you're looking for a HDR display, you can be happy with a "HDR" filter but also opt into DisplayHDR 1000 certified displays with 120+ Hz. For the entire Sweden because every decent Swedish retail chain and store is on this website, and they have everything between solid state drives and shoes in their database. If you look for watches you have filters and columns for e.g. automatic, solar powered watches, etc.
Amazon is very, very different. They're also a front to various stores but try to make it appear like THEY are the store when they are really not. Prisjakt instead just has this razor sharp focus on making you in charge of the data and forming decisions based on that, and then when the decision is made, presents you a list of the stores with that product and their respective prices. You are in control and maybe you prefer a certain one because you're a long time user there and like them.
So Amazon becomes a "fake store front" (like Sweden's CDON) and Prisjakt is more like just a database. One optimized for usability and presentation.
