Wouldn't the exposure be a function of how the camera senses and controls the light? Are you also sure you are using the EXACT same focus point? that's where the light metering is done so if you were just a little off and the focus point is a lighter shade than the next, then it would explain the exposure difference. The only way to be sure if your 550EX is mis-behaving is to mount the camera/flash on a tripod and take multiple shot of the same subject under the same ambient lighting condition. I bought a 580EX only because I needed a second flash on top of the existing 550EX, it's been very good, it's slightly smaller in size, the tilt/swivel head is much easier to use, setting changes using the rotary dial is more intuitive, although the only minor pain for me is to remember how to make certain changes on different flashes.
