Is Spigot or Bukkit Better?

Spigot was created from the CraftBukkit source code, but has been highly optimized for performance. Spigot is generally a better choice for both large and small servers, as it will use memory and CPU much more efficiently than CraftBukkit.

What's the difference between bukkit and spigot?

The main difference is the different philosophy. While Bukkit tried to change as little as possible to vanilla code and as safe as possible, while Spigot is willing to take more risks. For example does Spigot use protocol hacks to allow clients of different, incompatible, versions to play together on a server.

Is paper or spigot better?

Paper is generally considered to be more performant in direct comparison to Spigot due to further optimizations found in the server code. It also gives users control over technical parts of their Minecraft server, such as specific redstone features to disable, TNT mechanics, and much more.
