Key Differentiators
Dolby Vision: The Chromecast supports Dolby Vision; the Roku Express 4K+ does not (HDR10 only). On Dolby Vision TVs, this is visible in HDR content.
Google Cast: Native one-tap casting from Android phones and Chrome is the Chromecast's signature feature. The Roku Express 4K+ has no Google Cast.
Google Assistant: More capable voice search than Roku Voice for natural language queries.
Price: The Roku Express 4K+ is $60 less. For streaming-only households without Google Cast needs, this is a substantial saving for equivalent content quality.
