The only store that really stands out in that list is GOG so I don't really see it appropriately bundled with the others in the article. It's the one store with no DRM, you own the game. And you'll own it when the current owner/CEO dies and is replaced by a rent seeking MBA who charges you $10/mo to maintain access to the library of games you already "own" (for those who don't already do that).
For the rest of the stores some are better than others but at the end of the day they're "better features" rather than fundamentally better, like GOG is. Because ultimately what I'm doing is buying a game, not a forum or a review (as useful as those are), and definitely not renting a game.
This. Everybody must remember that Steam doesn't sell games. It sells a license to run games on Steam.
You "have" games on Steam as much as you "have" the apartment you're currently renting.
