Depends on the rims and other stuff. I don't think we can just willy-nilly slap on tires without regard to the rims and overall design.
700x25 felt splashy up front with my Ironman's Araya CTL-370 narrow rim. Felt imprecise on fast turns. Too wide for that rim. Feels fine on the back. But I prefer 700x23 up front. No problems mixing 700x25 on the rear for a little more cushion with 700x23 for handling, at least on my bike.
