I also had a Kate Spade rubber (or silicone?) case which I do NOT recommend. It was durable, but it stretched out badly in <3 months. The phone would slide around in the case or the case would pop off.
If I had to choose one case, I think I would go with the Rocketfish. It's cheap, durable, protects the phone fairly well, and doesn't pick up lint/is not sticky (while still remaining "grippy"). The only thing I don't like is the camera cutout.
I like the Incase Pro Slider a lot, but I do have concerns about the durability of the case and it's ability to protect the phone. I think a hard enough drop would crack the phone, which is not something I felt would happen with the Rocketfish or Kate Spade case.
