I disagree (partly), for the very first time you should watch the TV anime first because it's still a good anime worth watching on its own and you'll get to know Susumu Hirasawas Music which you can listen to while reading the manga.
Yeah, I agree. Not only do you get the added bonus of the fantastic music, but you can also read the dialogue from the manga in your head as the voices from the anime. I watched the anime before diving into the manga and I wouldn't have it any other way. If anyone ever asks me which to start with first I'll always suggest to go with the anime.
