Personally, it's not a significant issue, but it is a preference. Do you indent code when coding with braces? How anal are you about keeping your code formatted consistently (i.e. spaces after operators)?
Sometimes, not always. I'm likely to put a one-line getter/setter on one line.
I use formatter tools to do most of the formatting. It's nice to have formatted code, but I'm not fastidious about it. It's bound to Ctrl+K, Ctrl+D in Visual Studio. I prefix it to Ctrl+S out of habit. But if the automatic formatter can't take care of it, I don't bother changing anything. Simplicity and consistency are more important than "having my way".
Code should be readable, which is a human issue. As such, I think it's always going to have edge cases where "breaking the rules" is appropriate.
EDIT: Come to think of it, I often use the formatting as a pre-check before compiling. If the formatter doesn't format the code as I expect it to, it means I've screwed up a block somewhere. That's pretty much it for me.
