Halliburton vs. Schlumberger

VS

So here's the deal. I just recently got a job as a dispatcher at Halliburton. Here is the catch though. My fiance works as a bulk operator for Schlumberger. So basically we work for the two largest oil companies in the world. RIVALS!!!! LOL It's only funny because we keep fighting over which oil company is the better of the two and obviously we are both a little biased (hmmm wonder why). SO if you see this post maybe we can do some kind of online vote on which one is better. We'll be awaiting the results. Who will arise victorious? SCHLUMBERGER or HALLIBURTON.
