Things I care about are: ability to watch live TV, access to the major TV networks, ability to DVR, ability to watch things from other devices (like "I'm traveling but want to watch my DVR'd program).
Sling was looking good but doesn't include the major networks and only some of its channels can be DVR'd.
I thought about using an HD antenna and getting a hardware DVR like a Tivo or Channel Master DVR+, but then you can only DVR the major networks. If you try to supplement that with Sling, you're back to the same problem that only some things can be DVR'd. Also the hardware DVRs don't generally let you watch remotely, and the ones that do aren't as good at live TV.
Hulu Live TV seems good so far. You get access to live TV and DVR and you can watch from anywhere. But it also gives you access to its existing streaming library, so you have access to a lot of shows even if you didn't think to DVR them before they happened. At $40/month it seems like a pretty good deal (that gives you 50 hours of DVR). It's $44 to have "No Commercials" (this removes commercials from the streaming content I believe). If you want to skip past commercials in content you have DVR'd, you need to pay an extra $15/month, which seems kind of lame.
I wish I could try YouTube TV but it's not available in Seattle yet!
