Here is a link to a rather lengthy fact sheet about the different types of Insulin available which may help.

Haven't posted on board as it is much too long.
An extract from the report about the different types of Insulin.
Human and animal insulins
Human insulins are not superior to animal insulin – Cochrane Review, 2002
Rapid-acting insulin analogues
Rapid-acting insulin analogues have only minor benefit for the majority of patients - Cochrane Review, 2004
Rapid-acting insulin analogues are not superior to human insulin for the treatment of Type 2 diabetes - the Institute for Quality and Cost Effectiveness in the Health Care Sector [IQWiG], July 2006
Rapid-acting insulin analogues are not superior to human insulin for the treatment of adults with Type 1 diabetes. The benefits for children and adolescents are unclear for lack of data - IQWiG, June 2007
Long-acting insulin analogues
Long-acting analogue insulins can be used as an option for people with Type 1 diabetes but not for those with type 2 diabetes, except under special circumstances - NICE guidance.
Long-acting insulin analogues are not listed in Canada for treatment of Type 1 or Type 2 diabetes because they are not superior to NPH human insulin - Canadian Expert Drug Advisory Committee [CEDAC], June and Sept 2005.
Long-acting insulin analogues have only minor benefit, if at all, for the treatment of Type 2 diabetes - Cochrane Review, April 2007.
Details of the above Reviews can be found on our ‘Reviews and Reports’ pages:

Note: IQWiG is carrying out a review of long-acting insulin analogues in Type 1 diabetes and then there will be reliable evidence to inform decision-making for all insulin analogues in both Type 1 and Type 2 diabetes.
The conclusions from the evidence are clear – GM insulins are not superior to their predecessors
Hope this helps.
