Smart TVs and standalone streaming devices like Roku, Fire TV Stick, and Chromecast access the same apps, but a dedicated device offers key advantages. Performance varies widely across smart TVs due to differing processors and licensed software from Amazon, Google, and Roku. A newer streaming device often provides faster, more reliable navigation than an aging TV's built-in system, as it focuses solely on streaming without competing for system RAM.

Advertising is pervasive on smart TVs from brands like Samsung, Amazon, and TCL, whereas devices such as the Apple TV box offer an ad-free OS experience. Software support for smart TVs eventually ends, causing slowdowns; a streaming device is a cost-effective way to restore updates. Unique features include local media playback via Plex, lost remote finders, live TV integration, and gaming capabilities on units like the NVIDIA Shield. Finally, dongles and boxes are portable, allowing users to move their personalized interface between TVs or take it while traveling.
