Infor system family

Hi!! :)

i'm performing some market analysis concerned Infor ERP systems(thanks to Gartner Magic Quadrant it is really worth to explore) mainly for financial activities.

Could anyone recommend me which software would be better to look deeper inside:
I'm taking under consideration three Infror Systems:
- Infor M3 financials (Lawson)
- Infor Sunsystems 6
- Infor 10 ln Erp

Key system requirements:

- Access to financial module form Web Browser - it's crucial
- Scalable up to 5000 users
- International Capabilites especially for shared service center(busniess process outsourcing)
- eu IFRS support + local Gaap espcially for countries in the middle-east Europe
- open interface - in/out api e.g. general ledger, ap and ar, sales invoice etc.


Thx for help!
