Saving Throw bonus (or penalty), duration and on whom it works.
Charm Person -> +4 bonus to saving throw, works only on humanoids (like Hold Person)
Dire Charm -> no bonus or penalty to saving throw, humanoid only I think
Domination -> -2 penalty to save, works on anything (like Hold Monster)
Mental Domination -> Priest spell (unlike above three), don't know other than that
