You have to keep in mind that most radiators already run multiple parallel channels within (heatercores). The most flow restrictive radiators are those with a single channel. Adding another radiator in parallel is going to be just like buying a bigger one.
:shrug: maybe im just confusing myself, but water acts similar to electrotrickery in the way that it flows.

Almost there...
Yes, because the rads in parallel would make an overall lesser resistance to flow, it's better.
Individual components of the rads aside, they still need a minimum amount of flow. If you run them in parallel, and the flow through one rad falls below the minimum flow rate for the rad to be efficient, then you're loosing out on some cooling.
On the other hand, if the flow through the rad is still above the minimum, then everything is ok, in fact, it'll be better because the overall flow rate will be higher.
