Depends on how challenging the tempo is. If it's something you've got to work up to speed, work with the metronome first at slow speed, and when you're comfortable with full speed switch to playing with the song.
Either way, it's always good to play slow when you're first learning something. Sometimes people never get truly comfortable with something because they're always pushing the speed and don't ever have a chance to get comfortable with it. Get comfortable with it first, then bump the speed.

So if i learn a song to the song instead of playing to the metronome is that ok. Or is just using the metronome a better idea?

It doesn't really matter - they both do the same thing ultimately, assist you in playing in time.
