I have always been told to look at the three 'P's when describing sonar units. Power, Pixels and Price. The power, as you figured out, is how strong and accurate of a signal you get. The more power you have the more signal there is and thus the more accurate the returns are. The Pixels, much like a computer screen, are how accurately the unit can display the return. If the there are not a lot of pixels, it may not be able to show you the accuracy. Don't be fooled by the screen size. This has nothing to do with pixels. A 640 x 480 (pixels) screen could be 10 inches big or 5 inches big, depending on how big the pixels are. A pixel is nothing more than a light that changes color. That said, the more pixels, the more accurately the unit can display the returns. The third part is has the least to do with how the unit works, but the plays the biggest part of our decision and that is price. The key is to get the most Power and Pixels for the Price you are willing to spend.
OK, well, I didn't mean for this to get into that much detail, but that's my $.02. Hope it helps someone.
See you on the water!
