What's the difference in avocado oil and olive oil

I've never cooked with avocado oil, but it was my understanding that it had one of the highest smoke points of most common oils. See this chart: http://www.goodeatsfanpage.com/collectedinfo/oilsmokepoints.htm

Avocado oil makes a great finishing or dressing oil! But it burns quickly so I tend not to cook with it.

Olive oil can cook at higher temps than avocado oil.

Well, the main difference is that one comes from olives and the other from avocado's!
