In a nutshell the o.c. system pump output increases with pump (engine) rpm up to relief valve setting. At full speed of engine pump is operating at rated capacity the entire time (with oil being dumped back into the resorvoir if no valves are open). Cheap, reliable, limited capacity, and wastes energy by pumping all that fluid all the time. Closed center only delivers fluid as needed, increasing at an increasing rate up. Allows for higher overall capacity b/c you are not using that capacity all the time (would creat a huge power loss and waste heat probs if it was running wide open all the time). Much more expensive to service and more complicated but much more capacity.
