I think that at one stage you get an understanding of which features you need or want and look for cameras that meet these needs. I can not tell whether a photo was taken using Nikon or Canon. In most cases, I can not tell (without pixel peeping) and under good lighting conditions whether the photo was taken with my Canon G11 (a fancy P&S) and Nikon D300. I can often tell photographers apart. I think that there is a very narrow group of photographers with great skills and specialized needs that can coax better images from one camera than already superb images from the other. I doubt I could tell a difference but i do believe that they could. So - I just look for features I convinced myself I need, stay with the brand i already invested in and try to learn more about the camera and lenses i already have, while fantasizing, and sometime purchasing a new lens or other accessory with hope that i will be able to do what I could not do before. DP review is one of my favorite sources, but i do find the numerical score irrelevant for me, because the reviewers naturally value different features differently than i do. I enjoy chatting about cameras, but i just prefer photographing over shopping (most of the time).
