Strada = more comfortable... scratch that... MUCH more comfortable. Great interior, soft-ride, car-like driving dynamics, good power. - Better in-city or on-highway truck.

Hilux = more utilitarian... better able to carry heavy loads. - Better farm truck... but if you're buying this for work, might as well just get the 2.5. 4x2.

Of course, you can also look at the new Ranger (great engine and handling) and the new Frontier Navarra (same... great engine, supposedly good handling... haven't driven it yet) if you want a truck that will combine both utility and comfort.
