These is no "best" here, it all depends on your own personal needs. You'd be running the server, not us, so the only thing that matters is if you can work your way through these mods.
For what's it worth I'd vote
neither. There's nothing there which cannot be done in Minecraft vanilla, so why would you limit yourself to what that mod allows you to do? Reminds me of a mod, I think it's Essentials, which I deem pathetic because it doesn't understand command selectors such as @p, @r and so on.
Basically, if I want to give a random player a diamond sword:
/give @r minecraft:diamond_sword{display:{Name:"\"Shell's slasher\""}} then the plugin won't let me because it doesn't understand
@r. Some high quality admin plugin indeed (not!).
And that's also another concern: what if you'd ever start working on another server run by other people and you work your way up the ranks as admin? You might end up be fully depending on these mods without actually knowing any of the actually available commands, that can seriously hinder you.
My take? Check out
this list of commands instead. Make yourself familiar with location parameters and selection properties, and then you don't need any silly mods for all this.
