I don't pay much attention to other distros...could someone give an 
overview how Sci Linux & CentOS differ ?

A quick read of the CentOS homepage mentions their growing community 
base, quick errata release, 100% binary compatibility, etc.

The SciLinux FAQ mentions it is good for local institutions to customize 
to fit their needs (ie. scientific linux "sites"). My experience is 
SciLinux also has quick errata release, 100% binary compatibility, etc.

Cheers,
