Well, I guess I am also going to need your requirements over here like what do you want to do with your device? Anyway for the sake of answering if I have to choose from iPad5 or Samsung Note then I would go forward with the Android i.e Galaxy Note.
The only reason I love my Note 10.1, is the S-pen/stylus and the Snote feature to make notes, together with it's split screen. I got it after I fell in love with the Note3's (too small screen for making nice notes) handwriting recognition capabilities.
For any other work/apps/fluid operations/etc, I sometimes envy my friend's iPad, but once I've pulled out my Samsung Note's S-Pen in a meeting, I'm glad I have my Note.
