I have the Otterbox comuter case in white. I have the screen protector that came with it and its pretty nice! The only objection I have is after taking it off a few times the silicon has become a little loose... will apply my hair drier to it and see if it fixes anything. The other day my beer spilled over my phone and the silicon layer prevented it from seeping into the phone itself. So pretty good! This is my favorite case because it seems to protect very nicely without adding too much bulk. Also... I like to have protection for the all the places on the phone with plugs... and this one does it. I do feel that it is a bit hard to align the silicon layer that rests on top of the volume and power buttons at times and if they are not completely aligned, they wont work. The case is pretty hard to put on especial the first few times.
I also have the Incipio Sycrilic case and its pretty decent... but the area around the sd card/ sim card slot is a bit loose. It protects corners pretty well, but Im afraid if I drop it and it falls on the sd card/sim area ... it will break. Also... I ordered this one from ebay at 6 dollars! I ordered the pruple ant the metal like one. Upon receiving them one of them was broken on the upper part (around the camera)... contacted the seller and they shipped a replacement, but I do feel it is easy to break. Overall its pretty good. The volume and power buttons on this one are covered by the silicon layer, but there is no protection for the plugs at all.

I also own the Body Glove Encore case... but this one the least protective of all. Leaves the top and bottom completely unprotected. Compared to the 2 cases described above, it is the thinnest. Its a snap on, one layer case compared to the dual protection of the others.

I have Otterbox defender case. This one is the bulkiest of all. Besides bulk the thing I dont like about this one is the incorporated screen protector. Although the idea is great I know one day it will be very scratched.
In the end... I would recommend the Otterbox Commuter case because its not too bulky, and the second one I would recommend is the Incipio sicrilic, especially since Im not one to drop (this) my phone so much (never have). If your on a budget on the link I posted to it... you can purchase Incipio for $5.99 (4.99 for the purple one) with free shipping compared to the Commuter that cost me $20 and Defender that I got for $40.
Im attaching picutres of the first 3 cases in the mentioned order.
