I play Summoner/Phantom in JP and it's pretty good.
But it's also great if you play as Summoner/Techter if you're good enough. (I've seen some SuTe with insane skills)
The safest route is probably SuFi since Summoner class doesn't have JA to get a lot of boost from Hunter. That's just my opinion, take it with a grain of salt. To be real honest, I'd say just go with what you think it's best for you, there's not much pressure needed in choosing the right class and min-maxing just because! Unless you're aiming for the best, that's a whole different story
