I love the DuroCase I picked up a couple of weeks ago:
Amazon.com: DuroCase ® Motorola Moto X 2nd Gen. 2014 Kickstand Bumper Case - (Starry Night): Cell Phones & Accessories
It's a softer rubbery inside with a hard shell outside. The rubber is thick enough to be protective of the corners. The screen recess is plenty deep enough to be protective but doesn't interfere with screen access in any way.
The kickstand, while not great, is very functional and a nice addition that I have come to insist on for my cases since my Thunderbolt got me hooked on a kickstand on my phone.
The case fits, barely, into an old neoprene case I bought for my PalmPilot 3C years ago. It should fit easily into any number of leather cases available (anything built for the Galaxy Notes, for example). I had a cheap leather holster that fit my Optimus G Pro with the OGPro version of this same case on it, and it worked fine (and the OG Pro is considerably larger than the Moto X 2014). It was a super cheap leather case that fell apart quickly, but size-wise it was good, so there should be plenty of options there.
The case makes the phone much easier to grip by widening the edges so I'm not trying to grip it by the thin aluminum. It feels a lot less likely that I'll drop the phone and is much more comfortable in my (large) hands. The cutout for the "dimple" is very large and easily accommodates using the dimple for ergonomic grip. All other cutouts are pretty generous, with the possible exception of the headphone jack if you have a headset with a really wide plug (not a problem with any of my headsets, but some are a teeny bit snug).
It also flattens out the curve on the back of the phone a bit and leaves a "flat spot" about 3/4 of the phone wide while still tapering the edges to approximate the ergonomics of the original Moto curved back. This makes it easy to hold while still allowing you to set the phone down on a table and tap away at the screen without the phone rocking and spinning about like a Jack Russell Terrier.
Your mileage may vary, but for me this is the perfect case, and is available in quite a few styles. I bought my Moto X in black plastic resin without MotoMaker, though, so I don't mind covering up my phone.
