T-Mobile One Military vs Magenta & Magenta Max Military

Hello, 

I am in the same boat. I chose to stay with military one because I think you will pay more for Netflix and get less tethering per month. I think you can put the one plus option per line where with magenta you have to do magenta max with the whole plan at once. I don’t know how correct I am but I am hoping to find out the same answer.
