Cutting the cable, lets talk options and media setups

So is PSVue generally considered the best live TV streaming option? It seems to have most of the channels that we watch (outside of Nick). Is there a way to get the Nick channels?

I'm trying to convince my family that we could move to streaming services without losing much, if anything, but they're concerned about the convenience of it. My wife typically just sets the DVR to record something and watches it later, so the PSVue DVR capability is attractive. Is the interface intuitive and/or easy to use?

My main concerns are live sports (Saints and soccer), channel availability and convenience.. But right now, I'm leaning towards buying a FireTV for the living room, a Fire Stick for the other rooms, an upgraded router and a step up on my internet package. I think I could save around $75 a month. We're already paying for Netflix and Amazon Prime.

Thanks for any advice you can offer!
