The answer would be that it depends - which do you find easiest? Personally, I hate studying from a computer-screen - it's very useful being able to search the material to find an answer if you forget something, but I don't like it for studying in the first place.
But that's just me - everyone's different. Go into a pilot shop, have a look at each of them, and make up your own mind which you'll find easiest to study from.
