Hello,
I would tend to say that voltage-based designs have an advantage in speed and that there are some differences in arithmetics: it is easier to sum currents, but when calculating differences, you must avoid getting negative values.
The most important thing is that there are to my best knowledge little current-mode designs in commercial production, which IMHO means that they cannot be better than voltage-mode designs. I may of course revise this statement if somebody is able to mention current-mode based commercial designs.
