Here's my take on all this...

(yes, it'll be VERY one-sided. Ha!)
Pirates:
- Have guns, swords.
- Wodden ships armed with cannons.
- Are usually drunk and stink.
- Fight like cowards, run when outnumbered/outgunned.
- Work in chaotic groups.
- Only two cool pirates: Captain Morgan and Captain Jack Sparrow.
Ninjas:
- Edged weapons, wood weapons.
- Masters of stealth, deception and camouflage.
- Prefer to work alone.
- Requires the element of suprise to be effective.
- Looks cool in black.
- Only one cool Ninja: Snake Eyes (G.I. Joe).
Canadian Lumberjack Commandos.
- Have big guns.
- Have cool beards.
- Can easily demolish anything made of wood.
- Can work in groups or alone.
- Always carry a bix axe.
- Have an army of pets that can decimate wood just as easily. (Beavers)
I think the win would go to the Lumberjacks.
- They'd easily decimate the pirate ships which are made of wood.
- They'd easily decimate a lone ninja by cutting down all his cover and destroying his wooden weapons.
- They don't need cover to hide in. Hell, they usually wear red so you can SEE them.
- They don't need to be quick. They'll just mosey on and raze the landscape till the objective is completed.
- They'll always have a bix axe to use - and they know how to sharpen it on the field.
- They have an endless supply of wood eating minions.
- Their beards are cool.
