That depends. A lot of people find the manga to be better than the anime due to, well, stuff that I've never really understood. So if you ask me, it boils down to what type of person you are; out of these two variations:
1) The kind of person who reads the manga and then really wants to see the anime because it's great to see it animated.
2) The kind of person who reads the manga and then loses interest in the anime as a result, since the plot is already revealed.
So basically, getting into the manga will either fuel your interest for the anime even more or make it dimnish.
Try a few chapters and find out how you feel about it.
