The VOIA cover is thicker and stiffer which makes it slightly harder to put on the device. The boxwave cover is thinner and softer in the choice of material. The shiny part on the back of the boxwave cover shows fingerprints and I have usually never been a big fan of a case that has "buttons" over the buttons which is what boxwave decided to do on the power/volume button side instead of cutouts. While the cutouts on the VOIA made me have to relearn how to push the buttons (slightly) the boxwave changed the feel of the buttons which I didn't like very much.
Cost wise I got them both for about the same price, but the VOIA feels like a quality choice whereas the boxwave seems to be something where I don't feel like I got my moneys worth (not that either was expensive in any way...)
If you are looking for a simple cover and when traveling are planning to put the device in a neoprene padded sleeve I would suggest the VOIA cover over the boxwave. Especially if the prices are equal.
