I have 3 versions of Windows SBS 2003... what's the diff?

I have:
[*]SBS 2003 Standard Ed.
[*]SBS 2003 Premium Ed.
[*]SBS 2003 Std Ed R2

Is the R2 King of the hill?

SBS 2003, Release 2, has built-in WSUS services and native SQL Express 2005 pre-installed. WSUS is a free add-in to SBS, Release 1, but the integration isn't as good.

There are two SBS 2003 editions (both R1 and R2):
Standard Edition
Premium Edition

Standard Edition comes with an Exchange Server license, and a pre-built "CompanyWeb" instance of SharePoint.

Premium Edition adds an ISA Server 2004 (Firewall) license, as well as a "full" SQL Server license (SQL 2005, Workgroup Edition).

I just installed SBS 2003 Premium Ed. R1 but i've yet to run the config wizard. I have SBS 2003 Std Ed R2 so I suppose I could install that. But I'm wondering the difference between R1 and R2.
