What is the best delivery method for BW reports to a portal user?
A role-based information model. You can publish just about every report/query in the SAP portals. But it all depends on what the intent is to publish/distribute such information. If you are looking for a slicing/dicing capability only, then stick with BEx. If you want to have a common enterprise information delivery or 'functional' portals, then implement portal pages through Channels as container for set of BW reports.
