depends whats good for you.
Complete protection, or aesthetics.
I bought a sleeve case, the Sena Elega. I initially left ATT on the 11th with a silicone and plastic case, similiar to the capsule case, called incipio sylicrilic i beleive.
Anyways, I didn't like having my phone completely covered because so much of it to me is in the design. So I opted or a bodyguardz and the pouch. Now i feel safe about scratches and still can enjoy my phones design.
All said and done (not including the first case) i ended up spending like 65$ on the case/film. But it's worth it for ME anyways to protect my device until i'm ready to sell it and upgrade to the next best one.
Also this pic shows a iphone 2g but it DOES fit the 3g case. was snug for first week but it's loosened up nicely, still holds it snug but I can remove it pretty easily.
So this is what it looks like, and of course I have the bodyguardz as well.
