Well if I understand the terminology correctly, AP original housing indicates the housing used on a original handset. This can be considered as the original part just that it was part of an AP batch so warranty from manufacturer do not apply, just the same like buying an AP phone.
The AAA housing indicates the grade of the material and mechanical dimensions which is a near perfect replica of the original housing. For your information, in order to make a plastic mechanical housing of a phone you need a mold/die set to mass produce. Non-authorized manufacturers do not have the dimensions and mechanical drawings of these designs so they resort to replicating the mold/die set by inverting the design of the plastic mechanical casing obtained from the market. This process can never be perfect and can only be near the quality and dimension accuracy of original parts. Thus the AAA terminology.
The problem is traders/sellers often misused and abuse these terms to collectively call all of them AAA and even AP original housing because it holds better resale value and fools the unsuspecting customer. The price can often fluctuates drastically so you must judge the quality of the product you're getting. A good copy should have the following:
1. Refined and smooth finishing
2. If there are silkscreen logos, determine that it is aligned properly and is sharp
3. The casing should fit closely and not loose. Check that there are no large gaps
4. Determine that the new casing do not emit creaking sound when holding/using the phone
5. If applicable, check that the button operations are not obstructed by the new casing
