I'm using the Hyperion extended battery (4200 mAh) that comes with a new back cover. The color of the new back isn't an exact match, but you won't notice the difference once you put the Hyperion cover on it (sold separately). I actually like the phone being thicker now too. It feels more comfortable in my hand and it no longer feels like it will snap in half when it's in my pocket.
I really love this battery. It charges quickly and seems to last forever. It will easily last a full day with fairly heavy usage. It will last 2 full days with light to moderate usage.
I have a pebble blue S3, so I chose the black cover. It completely covers the phone except for the cutouts for camera, speaker, jack, etc. It makes it look like you have a black phone (which I prefer over the pebble blue).
The case has a honeycomb texture that gives it a little "grip", but it's still slick enough to easily slide in & out of your pocket.
CAUTION: The new battery and cover will make your phone exactly 5/8" thick, which I like, but you'll have a hard time finding a car mount that will hold a phone this thick (most accept up to 1/2" only).

They are as cheap as the one that comes with the phone is that's what you're asking. I got a case which fits the extended battery and gives it better tactical feel than the smooth plastic from the factory or the ones that come with the extended batteries.
There is a certain kind of soft rubber that some of those colorful "sleeve" cases use, and that provides a lot of friction. But those cases are really not that substantial. I can see why: they would deform too easily.
There are some hard cases that seem like they could protect the phone, but the hard plastic skates across the table almost as much as the phone without a case. (Such as the official kickstand case.) Those ridges look nice but when my hands are dry like they get in the winter or after washing, the ridges don't help.
TPU cases are interesting. The one that went with my old Hyperion extended battery on my S3 was the only one available that fit the extra capacity back. It had a nifty honeycomb looking pattern. But it didn't do squat to help my grip.
I have to wonder, why not cover the outside of those hard plastic cases with some kind of high-friction coating, or layer the soft rubber on top of the hard plastic? Cloth would be fine too. Something that actually creates friction, not just dressed up to look like it would.
