If you want to make one pretty quick, just use General Zoi's computer program (in DJ-DASH3's post). The OCs from that are pretty show accurate in terms of artistic style.
If you're talking about an artist to make them, well then "best" is personal preference. I suppose the "best" would be to get Lauren Faust to draw your OC, but that's not going to happen. In the Commissions subforum there are some people who will draw your OC for money (usually $5-15). You can probably also find some people on this forum who will draw for free (I must recommend @Rainbow Dashey for the work he did for me recently).
