It makes all the difference in the world. I use ProCamera because it has those options for video recording as well.
The exposure setting lets you control how bright or dark the picture is. You can focus the image so your chosen subject is sharp, not blurry, then you can adjust the exposure to make your subject however bright or dark you want.
Sometimes I want to make a picture even brighter than exposing for the darkest part will allow, so I cover the lens with my hand, set the exposure for pure black, and lock the exposure. Other times I want the picture even darker than exposing for the brightest part will allow, so I shine a flashlight at the camera, then set and lock the exposure.
Once you have the exposure locked so the image is as bright as you want, then you can set the focus for the distance to the actual subject you’re photographing.
Honestly, the biggest shortcoming in the iPhone camera is Apple’s decision not to make public APIs for directly adjusting the focus, exposure, white balance, and perhaps most important of all shutter speed of the camera. The physical optics and light sensor in the 4S are quite good, but without the ability to manually control them the camera is artificially crippled by Apple.
Independent focus, exposure, and white balance settings with the ability to lock them are the closest we have, and outside of Psonice’s magic with NightCap, there’s no control over shutter speed whatsoever.

I've been working some magic on the exposure + focus locking controls too, because I find this "square for focus, diamond for exposure" setup incredibly clunky
Camera plus was fast on my 3GS, 4, and 4S. Granted hardware has a lot to do with app launch speed and how quickly the camera gets going but it has always been pretty snappy for me.
According to my stopwatch, Camera+, Camera Awesome, and Camera.app (built-in) all take ago about the same amount of time to launch from cold.
When it comes to shooting speed, however, Camera+ is by far the fastest of the three, each shot taking about 0.7 seconds.
