The reverse of this question would be more appropriate to answer.
Debtors engaged in business would usually not like the prospects of liquidation and Chapter 11 might be a better option for such individuals associated with corporations and partnerships. Also, individuals with regular income if in a debt situation would be better suited to file a Chapter 13 bankruptcy.
Also, any person who has been granted a Chapter 7 discharge (or completed a Chapter 13 plan) within the last 8 years, cannot file for a Chapter 7 bankruptcy plan.
