You're comparing apples to oranges here. They're both great at their respective home ground.

Herc is arguably the strongest 4 star zerker (some say he's a hidden 5 star) with his skillset greatly prolonging his time on the field. Additionally he's able to get brave buster chains even without his NP, can buff his attack further and is overall a great choice against bosses/single targets.

Fran on the other hand is mainly used for her AOE NP to sweep up small fries/ deal considerable damage to all enemies at once. She's great for farming the daily quests, provided you can build up her NP without effort (Kaleidoscope/Waver/Mage's A. Uniform/others).

If you've just started though, I'd recommend prioritzing Herc, as he'll be handy to have during the main quests.
