True it's up to you , but I would reccomend the manga because it gives you a little extra insight sometimes into charcter's motives/ meanings etc. Plus the art is much better than the anime in my opinion. Oh and I know just the place for you to download it all with relative ease.

Naruto Chuushin Go to the manga section

I should let you know though that the site comes with quite a few pop-ups and ads, but otherwise is a great site.*

I warn you - you won't be able to stop at where the anime has reached and you'll read on til once again you'll be waiting a week at a time to get your Naruto fix. *sigh* Yes. It happened to me.


*This is the second time in quick succession I've hailed this site but I'm not associated with it or anything. I just like it. And I have a pop-up blocker which helps.
