The names look nicer when wrapped under an icon on the desktop or in a folder (I process a lot of pictures and videos, so using an icon representation rather than list or details works well for me); the extension (which I don’t hide, because I like to see what I’m working with) can often go on a line alone instead of being tied up to the last word in the title and causing a wrap in a word.
Sure, it’s purely a personal preference, but it’s one I’ve found I’ve kept to for many years now.
