Hamilton Healthcare Yield Maximizer ETF (LMAX.TO)

Boils down to individual preference on what you're trying to achieve. Owning individual stocks gives you more volatility, which can be to the upside or the downside. 

LMAX will give you more income sustainability. A traditional healthcare ETF will give you more diversification, less risk, but not quite as much upside as individual stocks. And if you want growth, and don't mind the volatility, you'll almost always see more upside if you pick the right individual names.
