The problem with the magus is that it just has too much baggage. That spellstrike thing? I don't know about Elric, but Gandalf never does that and neither does Corwin or any of his brothers. And it doesn't fit the fighter/mu from previous editions either. You use a sword so you can conserve your spells not so you can blow through them faster. The overspecialized magus spell list is a problem for the same reason.
These kinds of characters require a no frills 6 level wiz/sorc casting full BAB equivalent* class. Or in Gandalf's case a no frills 6 level druidic casting full BAB equivalent class. Also, most magic users in modern adult fiction use psychic casting components for decidedly non-psychic styles of spell. Magic words and gestures mostly show up in juvenile fiction.
* full BAB or medium BAB with a consistently usable self-buff that gives somewhere near (character level)/4+1 attack bonus. Clerics are full BAB equivalent with divine favor and after it caps out divine power. Magi are not full BAB equivalent because their ability to boost their weapon runs into the +5 maximum bonus cap on weapon enhancement and stuff like keen and shock are not of equivalent value to straight to hit bonuses.
