I agree/disagree with you. It'd be more like Priate vs Ninja... But I don't want to start that...
Klingons use shear strength and power to defeat their enemy. Vulcans, depending upon the time, would use Logic and Tech to defeat their enemy.
Both races really don't use emotions.
Klingons find honor in death. So IMHO, they would put more at stake and go after the prize. Whereas the Vulcans would make a 'tatical retreat' regroup, repair, rearm and go after them stinky Klingons agian.
I'm going to go off of my favorite era, TNG, for my ideas for who would win.
In space, it's pretty much a dead heat. I could imagine the start of a major war between the klingons and the vulcans, the Klingons would win hands down in the start.
They (Klingons), IMO, would use their cloak, sneek, and blow up ship after ship.
The Vulcans would eventually figure out how to see right through their cloak, and be able to fend off attacks.
Klingons would then use shear strength to try to deafeat the Vulcans... I can see 3 or 4 Klingon ships on one vulcan ship at a time, like pack hunting.
I can then see the Vulcans doing something to mess up the Klingon supply lines, and starving them from the inside out.
So, IMHO, the Vulcans would win the space war with great loss of ships, officers, personal, and resources.
Hand to hand combat on the other hand would be really interesting to see.
Vulcans running around like mongooses (sp) attacking the cobras (klingons).
Though vulcans have a more logical sense to battle, but there isn't any logic in battle, so IMHO the Klingons would win hand to hand.
So a total war between the two races, to me, would keep going indefinatly.
