Amazon Fire TV Cube
Score: 81/100
Roku Ultra
Score: 83/100Rankings
The Roku Ultra 2024 is Roku's fastest streaming player, offering 30% quicker performance, Wi-Fi 6, Gigabit Ethernet and premium Dolby Vision/HDR10+/Dolby Atmos support. Its lack of Apple AirPlay 2/HomeKit and a barrel-style power connector are notable trade-offs. Best for cord-cutters seeking top-tier performance and a feature-rich remote for a cinematic home-theater experience.
The Amazon Fire TV Cube is a hands-free 4K streaming box with a powerful octa-core CPU and full HDR/Dolby Atmos support. Its bulkier form factor, lack of gaming-focused features and occasional ad-laden UI are trade-offs. Ideal for Alexa-centric homes that value HDMI switching and high-speed Wi-Fi 6E.
