Steam vs Battle.net: Which PC Gaming Client Is Better in 2026?

Steam is the better all-around PC gaming client in 2026 — with 50,000+ games, Steam Deck support, Remote Play, family sharing, and the Workshop mod ecosystem, it's the default platform for most PC gamers. Battle.net is the mandatory client for Blizzard games (World of Warcraft, Overwatch 2, Diablo IV, Hearthstone) and Activision titles on PC — you install it when you play Blizzard, not because it offers a better experience. Most serious PC gamers have both installed. If you're only buying one client, Steam is the answer. If you play any Blizzard title, Battle.net is non-optional.
