Used the sword for a day and a half and first off, it feels great in the hand. Easy to slide in and out of my pocket, and great looking (handful of compliments).. I did however notice signal drop in my daily use. In my business calc class and in a restaurant I frequent, I usually get 2-3 bars. I had trouble holding a signal with the sword case. I didn't notice problems connecting to wifi, but it seems my downloading was slower.. Overall, I love the case, but I'll only be using it when I'm going to be in better coverage areas.
Used the Deff for the past day or so and I really like it. I don't notice any reception issues, feels nice in my hand, and I've also gotten compliments on it. It looks nice with my brushed aluminum backplate
Unfortunate about the sword, but it was free, so oh well.. I also decided the "dark blue" colored sword I chose is more of a light blue color. I was hoping the color in the pictures would be accurate as a grey-blue case would have looked nicer
