Steam had the distinct advantage of being first, and they've built a rich storefront with tons of useful features. Forums, reviews, discovery queues, recommendations based on your purchases, bundles, curators, account security (steamguard), etc. Valve also built a development ecosystem with integrated (optional) DRM, achievements, leaderboards, stats, multiplayer, voice chat, controller support with full remapping and such, just a ton of stuff. As a consumer, Steam is a much better platform than any of the alternatives. I prefer to buy games on Steam, all things being equal. As a dev studio, Steam takes 30% and Epic takes 12% (7% if you use Unreal engine).
