Let me give you the lawyer's answer: it depends.  Requirements will 
determine your answer.

Some thoughts that come to mind from your fragmentary remarks: If you 
require CORBA, you will have to build your own remote corba interface, 
so you might prefer a system that doesn't require you to do so.  If you 
require connectivity to databases for which Squeak doesn't already have 
a plugin, likewise.  If you require substantial cross-platform 
compatibility, look carefully at Squeak.  If you require access to all 
the sources and the ability to rebuild the system to spec from the 
ground-up, Squeak is free open-source, Cincom isn't.
