From what I gather:

Mifune is one of the best damage dealers (like in the top 5) in the game; he can one-shot bosses but he dies insanely fast (like two hits).

Magress on the other hand is a tank and when he gets to 7* not only does his SBB greatly boosts defense but his UBB also reduces all damage to 1 for 1 turn.

They're both great to have (so if you have them you should keep them both) it just depends on what you're trying to use them for.
