The fact that the elite is 4 pounds lighter is a big plus, but only if you have long hike to your hunting spot. With that said, it doesn't come with the comfortable foam seat with seat back that the standard Viper SD comes with. I can't say how comfortable the "lightweight mesh seat" is, but my guess is not very (i.e. you might as well go with a Wolf if you don't care about comfort and are more concerned with packability and weight).
I have the Viper SD and like it very much. However, with full cold weather gear on, the frame is a bit tight. If I could go back, I'd get a Goliath or Titan, just for the extra space. I'm 6'1", 220 lbs, so if you're not as big, it may not be an issue. I just wish it was possible to have a stand like the Open Shot with the seat of the Viper!
