Hi kdg4,
You brought up a really good point. I agree that one of the hardest parts for a project manager is choosing individuals for their team in a matrix-based organization. However, I also see that as a benefit. Assuming the project manager is able to gather the team members, they get to choose from a variety of different people, all with different talents and skills that incorporate to finishing their product, depending on what the project is. They might not get this benefit through a functional-based organization. This is because the same team members would work on different projects. These team members may lack the skills necessary in order to complete a specific project. Therefore, in this case a matrix organization may benefit the project manager the most.

In my opinion, it ultimately depends on the type of company and projects that the company produces. A project manager can thrive in any organization type. However, each organization comes with its own pros and cons. Therefore, it is difficult to choose the best type.
