Sasuke wins this
--With him having iintel on the basic mechanics of FTG,, sasuke would use his enton orbs, and all the other enton variants to flame the kunai and the locations with markings,, thus hindering minatos use of FTG
--Sasuke can also use his large scale susanoo variants and use their larger enton variants which would have the AOE to bypass the limits of FTG,
--once the AOE is covered minato would be unable to avoid the V4 bijuu slashes,,, and regardless of his perfect SM, his durabulity wont suffice such damage
--not only that but the AOE is covered before minato can prep frog song, and once the range of his FTG is bypassed, he is not managing to land the genjutsu without getting slashed by bijuu sized V3/V4 susanoo slashes
--Minato has no way of destroying sasukes susanoo,, as well as the fact that sasuke could track juubitos speed, and the fact that susanoo formation allowed itachi to defend against kirin means that even teleporting sasuke out of his susanoo is futile
