I suppose where money is concerned you cannot trust anyone

This is actually the best answer.
We don't have to trust neither Core, neither BU.
We have to read all we can and decide for ourselves.
From what I've read, what Core tell makes more sense to me than what BU team tells. But that doesn't mean I am right in my decision.
So, OP, let's make the question fair:
do you trust Bitcoin Unlimited?
