basically, kung ERP solution lang... they are almost the same.
though I would go for SAP since mas marami ang gumamit nito dito (e.g. Globe, PLDT, San Miguel, Digitel, Shell, Caltex, Petron, Cebu Pacific, etc.) and worldwide (60%+ market share). mas marami ang consultants na available both for implementation & support.
another + for SAP is that their newer versions offers a vast array of solutions... from billing to point-of-sale to RFID... etc.
