I've seen a lot of style wars - tabs vs spaces, braces starting same line vs next line vs omitted when possible, commented enums required (especially by European companies using StyleCop), etc.
All of that is unnecessary from a compiler perspective. But the style you are accustomed to aids your efficiency and effectiveness. Code doesn't care if it's consistently indented, but finding that unbalanced loop is much easier with it.
Use what makes you personally across all your development, and more importantly your entire team, faster and better.
