There are more important things to worry about.

If you are working on a team, do what the team does.

If you are working alone, do whatever works best for you.

This is the real answer. I personally like tabs. But I will absolutely not stand for anyone using tabs on our code-base. Because we use spaces, and we have better things to do that debate or, or reformat the whole code base. (even though we actually do use a style without alignment and so it would be not at all a visual problem)
