RE: new gun for fiance
Funny... I didn't want a gun for mine 'til 11 years after she'd become my WIFE!
Whoops - sorry: off topic.
Anyway, have her handle both guns, & see what fits her best. If she's already proven shecan handle thosecartridges with your rifle, she'll handle them even better in a rifle that fits her well. And both cartridges will handle just about every critter on this continent.
Take her to the store, and see which rifle follows her home.
Good Luck,
FC
