Everything but I will focus on the main point of the apps. Selling and managing games.

Steam store page has tags for what genre the game is and user reviews as well as information about system requirements. Plus links to click on to go to the developers and publishers pages to see what else they’ve made. You get plenty of information while it’s still easy on the eyes and digestible.

Managing your games with steam is a breeze. They’re listed down the side and the search is there and quick. Click on a game and get more information about it and see a large install or play button. Scroll down to see info about the latest update or activity from friends playing. Right click to get more information like where it’s installed locally.

Epic, at least when I last used it. Didn’t have user reviews, the page had large widgets for all the information making everything feel clutter while giving you less info about the game. Didn’t have tags and sure it did label the publisher but not the developers and you couldn’t click to see their other works.

Epic’s library management once again large widgets while giving less information. Feels cluttered. Install button is small. At the time I used epic there was not easy way to open install location. You had to go in file explorer yourself and find it.

While I’m on the topic of stores to why do console store pages suck as well compared to steam?! The console is literally sold at a loss and make money by selling you games but their store pages are shit compared to steam.
