Depends on who they're fighting. Remember that F/SN Berserker was horribly overpowered against pretty much everyone except Saber and Gil due to God Hand, and that's only because Saber had one of the best Noble Phantasms and Gil had overpowering f***ing limitless offense.
F/SN Bahsahkah was a lot more boring, though, definitely!
