You sir stated some fact but also there are flaws in your thread as well.Taijutsu: in the manga or anime it was shown that minato had great mastery over his taijutsu alike to naruto frog fu and tobi was said to be a master too.
ninjutsu: minato was pretty gud in ninjutsu not only rasengan cause only seeing a technic like biju bomb and create a virsion alike to it is a job well done by a master only. so does tobirama, because he was pretty good too using water style and others.
genjutsu:minato was not shown to use any of genjutsu doesn't mean he can't or doesn't know any, because a kage who was feared like minato and a guy who trash tobi who was known to control a jinchuriki and itachi master you know exactly what i mean, meaning tobi control kyubi with a mere sharigan just by genjutsu but couldn't put minato in a genjutsu. while tobi rama learn some genjutsu from his older brother demonstrated in the anime which means they both quite good at it.
sealing jutsu: minato was said to be a master of sealing jutsu, and tobirama must have know one or two if he created edo tensei but minato had the advantage.
kinjutsu: as shown during minato fight that he use his ftg kunai to take out every oponent even tobi got spearce by it so he was itachi level meaning a master of kinjutsu, on the other hand tobirama was a master too because of the thunder god kunai used by him.
summoning jutsu: minato was a master of it because he shown it during the nine tails attack and he was jiraira student you know was that mean, so does tobirama because of edo tensei.
space time: minato was a step ahead of tobirama in s/t ninjutsu because the naruto world fear him just for that.
senser or sensor: they both showed the same type of sensor.
speed: it was said that minato was the fastest shinobi in the naruto world shown during kushina rescued as a child, Fighting The raikage, and tobi attack, however, tobirama was fast but couldn't be as fast as minato even if he ussd s/t cause minato would have used his also. minato win this.
War fight: minato during his childhood and being hokage was feared by everybody even tobi who use this past through me on the other side i'll catch you technic ran from him and praised him for being worthy of his name and being hokage. while tobirama was not that feared. during the third ninja war the oder was to run if you can when you see minato because you'll die before you can think where to run. tobirama on the other hand was not that bad.
during the third ninja world that konoha win because of minato speed and s/t and fought an army at the bridge, killed them in mere seconds and returned to save kakashi, which means even if you are elite or not you'll die at the hand of minato in mere seconds and the only ninja who took more than seconds was A, killer bee, and tobi. that he didn't kill.
tobirama was face by 20 kumo ninja but got kill
