False on all counts.tobirama is faster has more chakra and power.
Sage mode does not prove one has more Chakra, only great amount of Chakra. And Minato is not very skilled at Sage mode.
Tobirama in official translation admitted Minato is better at teleporting. He did not say he is faster. What he meant by teleporting is not certain. I believe he meant Hiraishin.
Tobirama has more power. Minato has never shown his Sage mode lasts enough for him to use greater power and even if he did, Tobirama could still be more powerful. And Tobirama has many strong attacks. Also, if he is allowed Edo Tensei he has Gojo Kibakufuda.
