Very awkward, as it's very personal thing.
I have tried then both but sent the iPad back and stuck with Samsung, but I know the FE would find quality of life reduced without his iPad!
Obviously a Samsung tablet would be more compatible with His Note than Apple.
The other important aspect is music storage. You must make sure that whatever you get will take a high capacity SD card. I know most Samsung tablets will (I have 3, plus 2 notes!) but I don't know about the iPad.
I have no doubt someone with hands on experience will help you out.
Also on music, the Galaxy Pro 12.2 has the best speakers I have ever heard in a hand held device, at least as good as a table top radio.
