Key questions to ask would be: How easy customization is for the ETL and for the cubes/dimensions if you are using their prebuilt data pulls/cubes? How easy is it to schedule batch exporting? User maintenance - adding new users, cube/folder permissions. Custom calculations. User interface - web or installed windows program? Training - is training available for end users? via web?
