Quick answer
A USB hub adds ports. A dock is a hub + power + display output (often Ethernet too). If you only need a couple extra USB ports, get a hub. If you want a “one cable” workstation, get a dock.
Get a USB hub if you…
- Just need more USB ports for mouse/keyboard/mic.
- Don’t need dual monitors.
- Want the cheapest option.
