I am the opposite of the article's author. We switched from Roku to Chromecast. We actually now use the Walmart Onn Streaming boxes because they are cheaper, but in use they are exactly like the Chromecast. Chromecast and Onn run faster than our old, not Ultra, Rokus. I can directly connect my Bluetooth headphones to the Chromecast, where I had to connect the headphones through my phone. The reviewer complains about the menu of the chromecast, but you can change the interface to just show apps. Because the chromecast is android based, you can change almost everything.
Our tastes are definitely different. I did not like the original chromecast that did not have a remote.
In reality, roku and chromecast are very similar. I just prefer chromecast. It would be nice if Google would put out a higher end, faster Chromecast. Onn released a more expensive one that includes a smart speaker, but it is not significantly faster than their $20 device.
