SNC Integration with Ariba or HANA

Hi Folks,

We are planning to integrate SNC to Ariba or HANA.

Which one is preferable and what are the features/advantages we will get  on this.

If any one involved in Integration with Ariba/Hana what are the challenges we will face during that period.

I understand that SNC Enhancement package 4 will support HANA and PO collaboration views in customer view only re-designed with HTML 5 coding and if it true what about remaining views in customer view and supplier view including PO Collaboration view

Thanks and Regards
