Aside from the syntax (I find it ugly, you find it visually appealing - it's subjective), iostreams are inefficient, awkward to customise, not thread safe (allows interleaving), and mix format and data (that one is also subjective).

I love me some operator overloading. I love / for filesystem separators, I love | for piping things. I don't like << and >> so much but that's just because of too many years of writing them everywhere.
