Naruto wins this
--his firepower and durability are much higher than minato thanks to SM
--he creates many KB and gets them to fire off FRS and COFRS each of them which shit on minatos rasengans whilst the original fires SM TBB that are superior to minatos
--FTG really doesn't make a difference due to the sheer magnitude of their firepower as their AOE easily bypasses it's limits
--narutos link with kurama is also better than minatos, due to using his BM more times than minato meaning that his BM would last longer than minatos. And if minato falls to base. He gets wrecked with ease
--frog call can also be used to immobilize minato and allow naruto to land a blow. Or frog song can also be used to finish minato off
