Does not really matter. SSY is top-grade series and no reason to leave it for later, no matter how "heavy" it is. It's stuff like TwinTails, Madoka or Evangelion, which are either full of references lost on a newbie or a deconstruction of the genre it belongs to, that should be left till you've got some experience under your belt.

Well, duh. Hemotaste. I'm just saying it does not deserve all this hate it gets here. :P
