Best feeds to watch?

I just want to start a thread about the numerous feeds and sources available for this WC. I have access to a fairly large number and I have spent most of the Mexico vs South Africa match to test them. I stayed with the English language feeds as my Spanish gets lost with the high speed delivery of most Spanish language announcers.
In this match I tested Sling, a couple of IPTV feeds, Fox One and a very few others.
Sling - Had a great picture but had some little glitche where the video/audio would stutter.
The IPTV feeds were mostly OK but the picture was only average and the were frequent glitches and even one full cut out where the stream stopped and had to be restarted.
FOX One - the clear winner with absolutely no noticeable glitches and great 4K video and great sound.
The others I tried are not actually worth mentioning but they are also very unlikely to be used by me.

As a little aside: Landon was actually and surprisingly quite good as a color commentator. It seems FOX has mellowed him just the right amount.

I would be interested in hearing others experiences. Particularly those that use other sources like OTA or any of the other provider networks like Hulu or Youtube or any others.
BTW: My Sling subscription does not have locals in my area so it does not have FOX but it does allow FOX One to show me all the regular FOX content. I am actually very pleased with FOX One and its feeds.

Mods: If you feel this belongs elsewhere feel free to move it. I will not complain, at least not much, whatever you choose.
Thanks

Edit to add: Even though Sling does not show FOX they did have a feed for the match. I do not understand the nuances of what can/cannot be shown with a given package but, were i limited to Sling I would be OK with my Sling sub even though it does not include regular FOX programming.

 

I can, almost, get an antenna feed of FOX but it is so weak that the feed is unwatchable but there is stability enough to sort of follow the action. I briefly tuned to it and also watched the FOX One feed and I noticed no difference in timing except the FOX One feed seemed a little ahead.
There are many advantages to living rural but good antenna feeds of TV or even radio are not one of them therefore I have to rely on internet or cable feeds and I do not have cable.
I am glad to hear that Dish credentials work for FOX One as Sling does and that implies, now that we have two verified, that probably means that most of the internet TV packages will also work.
I do not think I have ever seen a picture on TV of a soccer match as clear and detailed as I have seen on FOX One. Now I sound like an advertisement.
If the rest of the Cup is as well televised as the first match was I will be a happy camper.

 

I wonder if there are different tiers of "4K" like there is for other lower resolutions? I am watching Sling 4K and, for me, it is also the best picture for a soccer match I have ever seen.

That is does 4K always equal 4K. (is that a video question or a physics one or a mathematical one or something else entirely?
