BES really does a much better job of integrating the Blackberry and your mailbox. The information's really all out there -- I'm just pointing out certain features that most people are interested in. With BES you're pretty much limited to one email address though you can still integrate 10 more via BIS as well. There's no 15 minute delay like BIS has as your email isn't polled via POP. You gain wireless sync of the contacts, calendar, notes and tasks. Most of the other major points are more beneficial in a corporate setting: generate & accept meeting requests, global address lookup, intranet access, various device management features, etc.
I use BES for my personal email but it seems like BIS is sufficient for 90% of people out there.

Though you can subscribe to hosted BES service if you or your company are willing to outsource email and BES.
