I have a hard time generalizing Otterbox as a favorite because they have a slim case that doesn't have a lip that protrudes above the screen. A couple of years ago, I purchased an Otterbox case and put it on my phone, then soon realized it had no lip that protrudes over the screen. I ordered another case immediately... and dropped my doggone phone while I was waiting for the new case to arrive. Yes, the screen cracked on a new phone. Now my new favorite case is a case that has a lip that protrudes over the lip of the screen, regardless of brand.
Also necessary: a grippy back. Many new cases are slick rather than being grippy. A slick case is good for getting a phone in and out of your pocket but is not so great if you're subject to dropping the phone. Therefore grippy back and lip around screen are at the top of my priority list, regardless of name brand.
For cases that are slippery, though, I've had some success with ordering pistol grip tape and carefully cutting it out in the shape of the case, then adhering it to the case. With a little patience, I've cut out a grip that appears like it belongs and/or that it came with the case.
I also like to keep a good screen protector on the phone in addition to a case with a raised lip.
