In C/C++ I'd be B, in java A but that's because everybody does it that way in java and I got used to it.

I'd be B here. I like my code to be easily readable.
But anyway, if you like to write code in a format that's not easily readable to everybody else and your editor is not able to format your code, you should look for another one.
I usually write something in a way that's quick and easy to write (but maybe hard to read), press CTRL+F et voila, everything looks nice (or conforms to some standard) :-)
Then it doesn't make no difference anymore if you type tabs or spaces.
