Most efficient Minecraft server version for 1.13.2?
Don't really understand the question.
As far as I know, vanilla is the "most efficient", it also has no additional functions. Bukkit / Spigot gives you the option to install plugins (practically everything goes with what you can imagine in Minecraft) but this also draws more power
The server doesn't have much power and I want to get everything out
Then vanilla, or spigot with plugins that improve performance
No, that's not really true… The vanilla lies like a fool
Now have spigot with no lag plugin
PaperMC is again significantly more efficient than Spigot. And since it is a further development of Spigot, you can also use all supported plugins under PaperMC.
