Softbank vs DISH: Which will be better for Sprint customers?

I am asking because I have no insight. My first reaction is DISH is a sort of Johnny come lately trying to c*ck block the deal with Softbank after the target they flirted with in the past tries to move on.

But I just don't know.

Is Sprint more or less likely to stay with unlimited data with DISH vs Softbank?

Which owner wants to place more emphasis on expanding the scope and coverage of the network?

Is this a black box where nobody has a clue?

Looking for answers since I am a sprint customer.
