I suggest that you drive them both, both in crowded areas and on faster roads. The seating position of the Honda is much more leant forward and maybe better for higher speeds, but the FZ6 Fazer is much easier to drive as an all-round bike. Performance-wise I don´t think there´s much between them. If you´re into sporting machines and also a easy to drive bike: Have you checked out the Suzuki SV 650 S? (I´m a FZ6 Fazer owner myself, by the way). Greetings from Norway, Oivind.
