does anyone have a Roku TV and/or sling TV?
If I buy a Roku Tv and sign up for Sling........ Sling has a cloud DVR service...... makes sense....
How do you watch and record local channels? I'm seeing there is an "antenna" (https://www.sling.com/supported-devices/antenna) I can buy for local channels over the air. Cool. But how can I record them? Do I need to buy my own DVR? And if I buy my own DVR, so I need the Sling DVR?
I always DVR shows so I can watch without commercials. Just trying to figure out the logistics of this before I start "cutting the cord".
Also, am I better off with an Amazon Fire TV than a Roku? Can I get Netflix/Hulu through the amazon TV, or only amazon prime?

I also have Hulu's Live TV with no commercials plan, Netflix, Amazon Prime, and HBO now.
Can't help you with the DVR aspect of this. The Hulu plan has a built-in DVR function, which I use for a few shows I like.
I did a lot of back and forth between the Roku stick and Fire Stick before making a purchase, and went with Roku...glad I did.
There is a TON of content available...MANY channels...via Roku once you plug it in. Some of it has commercials, and some channels are more obtrusive with that than others. The Vudu "free with commercials" content is not bad at all.
...router's in the living room, TV is in the bedroom. Have no issues whatsoever with WiFi for my laptop, but when I was using Chromecast, there were issues-a-plenty with buffering. The Roku + CLAIMS to boost your WiFi signal. Now, since I never used the "non-plus" version, I have no basis for comparison, but what I CAN tell you is that buffering now happens once in a blue moon and only lasts for 10 seconds or less. 99.9% of the time I get a good, consistent signal.
The other thing is that we have a flat-screen Sanyo TV, but it is NOT 4K or HD. When I went through the setup, it automatically tells you what your TV is capable of. For us, it was the lowest resolution (720p), but that is OK, because it's good enough for me. I have never been one of those "I MUST be able to count EACH nostril hair of the performers on my TV or I won't watch" guys (no offense to my audiophile / videophile friends out there). 
Our router's right next to the TV and right above the cabinet full of devices, so the regular would probably work for us.
I'm with you on resolution... we did finally upgrade to a flat-screen TV a few years ago, but that was only because the old cathode-ray-tube model was starting to do things like display part of the screen upside down! I do have some standards!! 
All I can say is that it works for me. We live in rural S.C., so our Internet ain't "fiber optic level," but it is fast enough for me. I've had much, much worse.
One time, during the mid-2000s, I lived in a townhouse in San Jose CA. ONE WEEK AFTER I MOVED OUT, AT&T had their fiber optic service up and running.
Roku handles low speeds (<10 mips) much better than Fire TV (I have both, and only 8 mips down), although Fire TV Cube uses Alexa, which is helpful. Depending on the quality of your internet, I'd lean towards the Fire TV Cube (I got mine for $70) since you have the added Alexa functionality.
As far as which streaming service to use, DirecTV Now is the best value (I've tried PS Vue, Sling, YouTube TV). It comes with 20 hrs of DVR space (which works well per my experience).
Good luck!
