I've got one of these JKase Diablo ones (it seems to be a common case with a few different names). My phone hasn't had any huge drops, but it's had no problem with the few small ones it's had. This case isn't very bulky, and it's got the nifty little kickstand (surprisingly useful).

Probably the Ballistic case that recently came out for the Nexus 4. Damn expensive though from their website, but $17 on Amazon currently. It's a tough dual-layer case, and I had one on my old Nexus S for nearly a year. Plenty of drops. Zero dings, scratches or other marks. Still in 10/10 shape.

The Seidio case with metal kickstand looks nice, but it's also $35 on amazon, which is pricey. ($35 on their site too. Talking about the Active, not the ridiculously overpriced Surface.)

I use this random JKase for Nexus 4 case from Amazon. It was $12 with $5 shipping to Canada, arrived in <~3 weeks (quite a bit considering it was just over the border in Saint Paul, MN). It does the job, has a kickstand, buttons and case itself are both grippy, and it's solid.

There's also the Ionic Guardian with those little button things at the back. it's a dual-layer case too from the looks of it, and it's only $9 on Amazon. Looks decent, has good reviews on Youtube, but I didn't bother with it as the JKase was only slightly more expensive and had a kickstand.
