I use both equally. Hulu is great for current content and it seems more like a TV replacement. But the movies on Hulu suck. Netflix has awesome movies. Its TV series is improving, but it will often get a series months after it airs. Theres definitely a place for both services.
I only pay for Netflix right now because the Plus offering for Hulu just isn't there yet. A ton of the content isn't available on mobile and the buffering can be terrible at times. Also they claim to keep full series of shows for Plus members, but when I tried it out I couldn't find historical seasons for many popular shows that I had wanted to watch and start from the beginning. So that pretty much killed it for me.
Recent episodes are not always free. I was using the free only version until "HuluPlus" episodes started showing up that I wanted to watch. I pay the $8/mo and I watch about 4-5 shows that I have subscribed in my RSS feed. Seems reasonable. I get probably 3-4 episodes per week for $2. Cheap entertainment.
