Samsung Galaxy Pro 8.4 Tablet Vs Samsung Galaxy Note 8/ 10.1

[GWC]

Evening all. Any views on which of these would be the best? My wife is looking for a tablet and has narrowed it down to these three through reading reviews on the net. Any stand out features or real downsides to any of them, or an alternative that does the job better for similar money?

I know the sum total of zero about them so said I'd ask the PH fount.

TIA
