While I'd definitely say that I tend to lean towards leaving the www. off of web addresses, I can see why some people would lean towards using it. The www. is a visual cue that lets you know you're looking at a web address before you even consciously read the web address. Incorporating the www. to avoid visual discord on a layout, where symmetry is perhaps a matter of necessity, is a bit of a stretch. My suggestion, in that case, would be to either use all lower case letters, or if you prefer to capitalize the first letter of each word, use a capital C on the .Com. It's not like it matters anyway.
