Tim,
Have not downloaded because my Windows laptop has Windows 7 but plan to upgrade.
Nodes are much more flexible, present more ideas but can present challenges. Just like setting up bins or events an your NLE of choice, the node tree must be organized, even more so. Should you or someone else need to go back to the project, a mangled up flowchart serves no useful purpose. It needs to be where anyone can at least understand what is going on under the hood, let alone allow for better troubleshooting.
Sometimes layers are a more appropriate choice. Why use a screwdriver to put a nail in the wall when a hammer is much better?
For processing stills or some basic animation nodes offer much flexibility, just on a single shot basis, like a scene. Great masking tools, color correction and such is why Fusion would be used for some work. For additional animation and timing, Motion is the tool of choice. Screwdriver or hammer?
At least that is the awnser I can think of at this moment.
Oh, looks like Fusion has an awesome particle system. Nearly forgot that one!
