Twitch at least "won out" over competitors by just being the least terrible streaming site for the most part. Now it's gliding along purely on inertia. They haven't innovated or brought anything important to the table, they're just the biggest player at that table

Curse I'm admittedly more than slightly biased on, since I used it basically from its inception back in the World of Warcraft days, because that's all it was initially

Curse was the least awful way to manage a bucket load of WoW addons, almost like how there are package managers for Linux today. It simply provided some central place to manage and keep mods updated, especially ones that would break whenever Blizzard patched it

Curse at least, slowly evolved into this hydra-like monster, trying to split itself off into as many different things as it could. The most insidious one I remember was when I reinstalled it (for trying out the newest World of Warcraft expansion at the time) it'd evolved far beyond what I expected

Upon relaunching my system it prompted me to add literally every friend I had across Skype, Steam and League of Legends. While also overlaying its voice chat system when playing certain games (League and TF2 come to mind)

Keep in mind I never used any of these features, it was simply new garbage that Curse added to try and stay "relevant"
