Blood glucose targets to be honest are a personal choice... I run of the opinion that the 'average' normal person has blood glucose in the range of 3.5 mmol/l - 5.5 mmol/l 99% of the time and thus maintaining this level would most reduce the impact of diabetes..
Clearly maintaining such tight control presents issue in T1 and T2 and thus a balance between blood glucose, lifestyle and health-risk (specifically hypo's in insulin controlled diabetics) must be considered.
My personal opinion is that as a T1 or insulin controlled T2 you should be aiming for sub 7.8 mmol/l @ 2 hours post meal... most the research papers I have read agree that sustained blood glucose levels in excess of 7.8 mmol/l damage the body and cause complications..
For non-insulin controlled (or other insulin inducing drugs) T2 i.e. those that maintain a level of pancreas function and don't run the risk of hypos I would argue there is a case for tighter 2 hour post meal numbers.. again from what I have read damage to the insulin producing beta cells starts with blood glucose levels over 5.5 mmol/l and therefore in order to keep you control and if your still reasonably young perhaps even improve your pancreatic function you are best to try not to go above this level all to often.
At the end of the day it comes down to personal choice.. All I would say is that make sure when you make the choice you are well informed.
