I had the Body Glove case for about a week (no belt clip). The texture is really nice and grippy. My issue with it was the thickness. The Hero is already kind of a stout fellow; With this case, it just felt so chunky. It also felt like my typing was being impeded when tapping keys along the edges.
I switched to the Seidio Innocase, and I've been using it for months now. It's a very slim case. It's a little on the slippery side, but it's not a deal breaker. I'd probably recommend this case first and foremost.
(I also had the HTC silicon case, initially, but it was terrible. It was an ugly, sticky, dust magnet. And it always felt loose.)
