This is a good comparison, Vanu Sovereignty is best Sovereignty and Twilight is best pony!  
It’s fitting they go togeher.  
(Also they’re both purple. )

@Ball Joy  
By being a B*tch to see at night.

Our foes will know the will of Vanu

@Madpony
 
History has never been kind to fascist empires. You’ll go the way of the Dodo like all the rest….if the Vanu don’t “accidentally” blow us all up with some alien toaster they fiddled with.

@Zincy  
Terrorists like you will never win.

@Madpony
 
BAHAHAH, superior firepower? Your glorified bullet hoses are nothing but bb-guns on steroids.

@Pathfinder  
You’ve made a good choice, soldier.  

@Madpony  
I like liberty and mysterious alien tech but come on! This music leaves me no choice. Burn the traitors.

Live free in the NC! Freedom or Death!

@Pathfinder  
Oh, and as for that musical number you needed:  
Loyalty until death.

@Madpony
 

 
Come again? I couldn’t hear you over the sound of TR pigs being gutted.

@Pathfinder  
The Vanu Sovereignty are a group of dangerous religious zealots, and the New Conglomerate are just a bunch of anarchistic punks. The authority of the Terran Republic is the only answer.  

@Pathfinder
 
The New Conglomerate is the only path to lasting peace and freedom on Arxris. Your choice is clear.
 
Seriously though, I’d go with which ever you enjoy playing the most. I went NC because their guns are the most fun for me, meaty recoil, high stopping power, and lowest ammo count. Heavy hitting weapons that require skill to use, and makes mistakes very costly.
 
TR guns are bullet hoses that are only effective with sustained fire, and VS guns are flashlights. Could never really get into either.

I have problem with Planetside.  
-I like best of ideology New Conglomerate  
-I like best the aestehetics (music etc.) of Terran Republic  
-I like best the gameplay of Vanu  
Which side should I choose? I need some kind of musical number to help me decide.

Vanu sovereignty as laser weapons are cool.

canonically we have no idea if luna values freedom or if shes a dictator or anything. however, we do know she at least at one point / still is a royal leader above the populace. that’s a point for NC [some are better than others].
 
but yeah discord fits NC better

Discord fits NC better. Don’t really know where Luna goes.

Liberty or death! My life for the NC!

Oh god. I love Luna, but I also love the Vanu. Who do I swear allegiance to!?

Vanu for life
