On this point, there are two main reasons why the AU will actually do a poorer job as far as security in concerned.  First of all, there are no assurances that African countries have the necessary expertize or financial capacity of supporting a well trained and always prepared military force. Only one country has a top military, Egypt,(1), and this is largely because African states cannot support big militaries of their own so how would they additionally support an AU force?  On the other side, we have seen the international community engaging successfully in peacekeeping missions, helping local governments defeat rebel groups. There are currently have 15 UN peacekeeping missions(3) in Africa and French troops are helping to stabilise Mali and the CAR(4).  Moreover, the institutional drawbacks that apply to the UNSC unfortunately apply to AU as well. The AU has 53 members and for an intervention to be accepted they would need a two-thirds approval rate. These alleged military interventions might get stuck in the same institutional gridlock as in the status quo. There even are some cases, like Congo, where other states (Rwanda and Uganda) actively supported anti-government Congolese rebel groups(2).
