Reading the book is of course better than reading the manga in that it has far more details in it. But, as it is a book, it only has like 10 or so illustrations per book, thus it will be text-heavy, i.e. a lot of text (though the style of writing is pretty much simplistic, at least in fan translations).

If you want a continuation of what you saw in the anime, your only choices are either to wait for an anime sequel (which isn't confirmed), or read the book. The manga hasn't got that far in the story yet, so you can't read a continuation of the main story via the mangas yet.

Though you could read Progressive and Girls Ops mangas, as the first tells stories that the anime either messed up (greatly...) or omitted, but that is pretty much a prequel to the main plot in the Aincrad arc (up to episode 14 in the anime), not a continuation of the main story, while Girls Ops is a spin-off that doesn't really have any connections to the main plot.
