The Magus appears to have 3/4th BAB, 6th-level spellcasting, two good saves, and some class features which synergize with melee weapon use.
However, the Eldritch Knight has better BAB, can go up to higher-level spells, a higher Hit Die, but only one good save and less class features and bonus feats.
If I wanted to be an arcane gish skilled in melee and magic, should I go Magus or Wizard/1-level Fighter dip/Eldritch Knight?
