I like SoM more than SD3, mostly for the mulitplayer since all the characters are easy to use and in SD3 you can have friend join but he'll have no idea what to do with the characters. Also I feel like SD3 has a bunch of padding with the mana beasts and having to find rare drops to upgrade to the last class (yeah I know Sage Joch but at least his stuff was short)
Music and atmosphere is lot better in SoM than SD3, SoM had the more fairy tale look and charm with it while SD3 felt so generic JRPG.
