I'm considering going back to Sling, mostly because it offers a channel my wife really wants. I don't use DVR (probably should). But I'm hesitant because a couple years ago Sling's streaming wasn't very good. I often went to WatchESPN and checked in using a Sling credential rather than watching stuff through Sling directly. PSVue doesn't have that issue (at least not as often; the NBA Finals still stuttered for me).
Hulu looks interesting because (i) we already pay some of that fee as Hulu subscribers and (ii) it has that CBS Sports network with 1-2 BYU games each year that I otherwise have to mooch off friends with cable. Still doesn't have Hallmark, though.
