It may just be your level of comfort as to which camera you prefer. I am a big fan of Canon, owning an AE1 and an A1. Both are beautiful cameras. However, unless you get the pro models, some of the functions/buttons are redundant. For example, on the Canons, there is a portrait mode which is nice but many believe redundant. You are better off in one of the other modes (app. priority, shutter priority, etc.) so you can make a better photograph and capture what you want. All of the other buttons on cameras these days are for quick pics. The custom modes are good when you learn them.
