With a series system branching from and returning to the same pump, I
think you might get some advantage in mass flowrate. It might be higher if the overall volume is greater than a comparable series system. If it's the same total volume as an series system, don't think you'd see any flowrate advantage. But you could probably use the same size radiators.
Series might be tricky since one radiator is going to see hotter coolant. Different sized radiators? Can't think of any real advantage to this, other than simpler piping. Mass flowrate can be bumped up with larger hoses.
