Jemacc is correct in asking you to evaluate what's important to you; but in general, if you're doing business, I strongly recommend that you have both person and company in your table. If the person you're dealing with is representing him/herself, you can always leave the company field empty. However, if you're dealing with a company, you always want to know the name of the contact person. You would never leave that person's name out and just put a company name. You're asking for trouble if you do. Always have a contact name and phone number or e-mail address.
