What is better a profile or a Facebook fan page for any business?

More than average people use facebook only for personal communications and not for business. You can use this as your advantage. State all your contacts that if they want to follow you in a professional terms then they can use their fan pages.
Facebook Group for a business is a big NO-NO.
You shoul never opt for groups as they are outdated and do not support Facebook Markup Language (FBML) or Facebook Apps, so they are not as interactive. Additionally, don't create a personal account (a regular Facebook profile page) for your business. You're supposed to use your real name and you're also only supposed to have one account.
Make your Facebook page worth remembering to your users?
If you think that only content of your page can do tat for you. Well then you are wrong. Your fan page reflects your business and make it easier for your users to find you easily on facebook. Once you get 25 fans, you can set up a username which makes accessing your profile a lot easier.

Customize your Fan page.
Start with uploading a profile picture and start filling out the relevant details about your business. Give your contact information and a brief history of your business origin and your future goals.Understand that they are landing on your page because they want information.

This means there won't be requirement for a dedicated person to sit behind your page all day long. You can feed all the post beforehand that can be posted to the wall exactly on time with final adjustments made.

More of community interaction should be promoted.
Ask your fans questions or share cool company or even personal insights with them. Give them a reason to want to communicate. Let your fans add up information in your page.
EdgeRank is Facebook's own algorithm to determine visibility on a user's home page. It takes hold from three main components: (1) the affinity score between two users: how often do they interact?, (2) the type of interaction and (3) the length of time since the action was done.
