It's an incomplete picture if you ignore the fact that videogames are infinitely more mentally accessible. There's plenty of very cheap, very fulfilling things to do with your time but they don't provide the instant, accessible dopamine hit that movies or videogames do, which put them out of reach for a lot of people.
I don't really watch TV or movies, and I play videogames pretty sparingly. I'm definitely glad I did it, and I find my hobbies now a lot more stimulating and rewarding, but I'd be lying if I pretended it wasn't a somewhat difficult habit to get into.
(I'm defining better as wider and deeper selection of books and ignoring anything else, like other library services, library hours, whatever.)
Of course I could have gone to the library, but I read a lot more if the book is a tap away on my tablet.
In short: you should start reading more books if you want books to hold your attention for longer.
