Since i work in the IT department for a local snackfood manufacturing firm, i have already evaluated SAP (Business One and mySAP) and Oracle Apps last year. In terms of functionality, they are almost the same except that SAP has packaged solutions that would work for certain industries. In terms of license costs, SAP Business One and Oracle Apps would roughly be in the same area with mySAP costing around twice as much.
If price is no object, the important thing is the implementation partner. SAP and Oracle Apps only sell the licenses. It is the implementation partner that does the actual implementation, configuration, rollout and turnover. Look at their past implementations and conduct due dilligence on them.
