If the USA app is anything like the other ones I've used when my DVR missed something that wasn't available anywhere else then you'll also have to deal with non-skippable commercials as well. Whether or not that's a big deal to you is your call, but personally that alone makes Hulu worth it to me.
I actually watched the whole first season on Hulu just last week before starting on the new season which I'd recorded on my DVR so now I'm all caught up. I watched the pilot last season, liked it well enough but had too much other stuff going on to keep up with it every week, even though I did DVR the entire thing. It was just easier (and no commercials to fast forward through) to watch it on Hulu since I have that anyhow.
ETA: Also the USA, SyFy, Name The Channel apps always seem to have a slightly lower quality than the same thing streaming off Netflix, Amazon Prime or Hulu; I don't know why, but that's what it seems like to me, especially at the beginning of an episode. If worse comes to worst you could always sign up for Hulu's free trial week and watch it, then cancel before it tags your card.
