My wife and I use Netflix + Playstation Vue. (Plus Amazon Prime Video, which we don't use a lot.) You don't need any Sony devices to use Vue – I didn't even have a pre-existing Sony account before subscribing. For whatever reason, my wife vastly prefers just being able to throw something on in the background or channel surf, rather than picking something specific to watch. And I like being able to watch some sports. So some kind of live TV service works for us.
We tried Sling first, but the quality of service was really bad – frequent hitches in the stream, or switches to low-res for extended periods of time, slow channel switching. A lot of these things improved a bit over time, but never to the level of Vue. (This was last summer/fall; I don't know how it is now.) The Sling app (Apple TV, Amazon Fire TV stick) was worse, with no traditional guide view. Vue's cloud DVR feature is really handy.
Vue's not perfect; the UI could be better still, and it's not as reliable as Netflix or traditional TV services. But it's mostly been good.
Note that with both Vue and Sling, you can sign in with that account to a number of channel-specific apps (FX, Bravo, Fox Sports Go, etc.) and get easier access to on-demand streaming of their specific channels. It's generally not that different from what's already available right in Vue, though. You might just prefer the user experience, or one version will have no commercials. That kind of thing.
Note that if your ISP has any kind of data cap, a live TV streaming service can eat a lot of bandwidth, depending on your habits (like if leave it on in the background like people often do with traditional TV).
