I would go with an AppleTV before I went with Roku at this point. I've noticed that, more recently, the Roku devices seem to be struggling to keep up with the newer apps that need a better, easier to use interface. There's been a lot of negative feedback from the app designers to Roku about it, and Roku is supposedly working on fixing it so that the app designers have more flexibility.
That said, I'm changing over to the Amazon FireTV Stick (I have two of them now). They perform flawlessly for everything I've used them and also have Alexa built into them. They run everything I need them to, including Plex and Playstation Vue.
