Better Buy: Intuitive Surgical, Inc. vs. Accuray, Inc.

New drugs that improve treatment often get a lot of attention. But in recent years some medical devices have arguably had just as much impact as many of these drugs. Two companies making such devices are Intuitive Surgical (NASDAQ: ISRG) and Accuray (NASDAQ: ARAY).

For investors, Intuitive Surgical has by far been the bigger winner. The stock has more than doubled over the past five years and is up close to 80% so far in 2017. Accuray stock, on the other hand, is down over 20% since five years ago and is up just over 5% year to date. But that's the past. Which of these two medical-device stocks is the better choice for investors?
