Using the same model in each location is the only sensible thing, so the familiarity will make every room usable!
Then it comes down to which model you choose. I think the 890-990 are the only ones to consider. The 990 is head and shoulders superior for viewability and hard button visibility.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
