My opinion; there might be some difference between your "sample roasters" outputs, but not enough that I'd worry about it. If a sample is good out of either one, you'll know it, and if it's a dog you'll know that too. IOW, you may be overthinking it.
If it'll help you sleep better at night, just keep roasting samples in your old/familiar setup, and then start practicing with the Quest until you think you know it equally well.
