Personally, I think what happens in the manga that differs from the 'Claymore' anime is much more interesting and worth the read. It does get slow in some places, especially during the exposition-heavy parts, but the plot is great - it delves into the Organization and the characters are developed much more - and we get to see a lot of cool new characters.

As for how long it continues on, the anime stopped around chapter 70 in the manga. So, since the latest update, there's about 80 chapters' distance in length. Be prepared to spend some time if you want to read it all, but I would still recommend it.
