Probably hard to go wrong with either but I would pick Martin Brothers.

I think they have shown many times they will do what the customer wants even if it is different from what they would do.

That being said if it was too different from what they want they may not take the job. I think he is particular about what has his name on it.

Of course dealing with either company in the real world may be a lot different that what is on TV.

I just hope they sign up for another season of Iron Resurrection. They had a five season deal and they just completed the fifth season.
