The problem with smart stream is the cost. At any point something could happen to cause all this to dry up. At almost $500 I just don't know if it's worth it for a little bit better interface and a few more options.
For $50 if all the streams dried up and the box because a brick it's no big deal.
Saturday was my old lady's birthday so I didn't get a chance to hunt around for the UFC but I'm glad it was on there. What stream did you use to watch?
