Would a green screen look better against blue material?

For my film i need to greenscreen some Roman Auxiliary troops(Blue tunics and shields) and composite them atop a wooden fort (Miniature) i was just wondering if i should use a green screen or blue? they both have their advantages and disavantages that i can see:
Green:
+ would not mix with the blue costume- easier to cut out from the screen.
- Has the green outline that makes it less authentic.

Blue:
+ Looks better.
- May cause the blue costumes to be cut out during compositing.

I've done some searching on the foums but wanted an answer for my own scenario.
Thanks and sorry for the completely noob question!

Erm, you will get spill from either colour but using software like CompositeLab or VisionLab you can get rid of this spill. If you are filming blue uniforms then you have to use a greenscreen (also green tends to work better than blue with digital equipment).

Also, blue doesn't necessarily give better results - in fact, if you're shooting on digital video it's more likely that green will give better results, due to the way the colour is picked up.

If you light and composite your greenscreen correctly you shouldn't have any green outline at all. A bluescreen is just as likely to have an outline if it isn't used correctly.

As schwar says, a well lit greenscreen composited with good software will produce great results. With digital video green is always more preferable, unless you happen to be filming green coloured subjects.
