truthfully do not see how PSO is better than PSU. yes the mission system could have been done better in PSU as well as the class balancing but there's a lot of things that PSU has better than PSO.
+The battle system. being able to switch weapons real time (and carry six sets) and melee now get attacking skills is way better
+no job restrictions.
+better graphics
+partner card/room system.
+PM's could have had better AI's but were a nice touch.
That's not to say PSO sucks which it clearly doesn't, but to say it's better is a bit much.
