So here's what I'm finding out (other than this sh!t is frustrating as all get out to get straight).
All streaming devices and services are not equal and at times, exclusionary.
Samsung smart TV's do not have an app for the Sony streaming service, PlayStation Vue (but they used to).
Charter\Spectrum Cable does not have an app for Amazon's Fire TV, but they do have one for Roku and just about any other streaming device.
You can't watch current episodes of The Walking Dead on Hulu.
Live streaming services like Hulu Live and PS Vue are more pricey ($40\month and up).
I was able to talk Spectrum into changing my internet from 30 mbps to 200 mbps and give me a comparable cable package to the one I had with Time Warner for the same price and got a bunch of extra movie channels thrown in for a year.
My house is 100+ years old and not entirely wired for modern technology, so I'd rather stream stuff via wifi or watch broadcast programming, since my reception's pretty good.
Since Roku is Spectrum compatible, I can use that as another cable box via wifi. That saves me all kinds of headaches.
For now, we're gonna stay with cable, but will be exploring more options over the next 12 months.
We also just bought a UHD smart TV and the voice remote is stupid easy to use\find programming. The picture is awesome, too, but if you're signal is low res, a 55" UHD TV will make that readily apparent!
