Each streaming device brand uses a different operating system, with many opting to go with their own proprietary interface. Though they all offer the same core features, some people may prefer one platform's visual design and organization style over another.  Here's a rundown of different streaming device brands and the current interfaces they use: Roku: Roku OS Amazon: Fire TV OS Google: Google TV Apple: tvOS Nvidia: Android TV (similar to Google TV but an older system) Though a few niche services may be missing on certain operating systems, they all offer access to the same primary assortment of popular apps. Navigation style, personalization options, and extra features differ across each system, however. Generally, we prefer Roku's interface for being the simplest and most reliable of the bunch, but some may find its look to be outdated compared to other systems that use a more modern, content-focused take on organization.  Every OS has its own advantages and drawbacks with a lot of their appeal ultimately coming down to personal preference. But no matter which one you go with, they all deliver the same basic streaming capabilities.
