In the health-care sector, few stocks boast names as well-known as Medtronic (NYSE:MDT) and Abbott Labs (NYSE:ABT). Medtronic's leadership in the medical device sector and Abbott Labs's strength through medical diversity has made it a strong stock for years. Each stock also offers a reliable dividend, with both Medtronic and Abbott belonging to the S&P 500's Dividend Aristocrats-the group of companies that have raised their dividends annually for at least the past 25 years.

But which of these dividends is the better buy? Abbott offers the higher yield by a slight amount and is well-suited to keep that dividend growing with its strong nutritional business and diagnostics unit, but Medtronic's growth in up-and-coming medical device industries and dominance in major niches such as cardiology make it as reliable a stock as there is in health care.

Find out the winner in the video below, as Motley Fool contributor Dan Carroll takes you through the strengths of Abbott and Medtronic's dividends-and which one should be the right call for your portfolio's health.
