I'm exactly the same. I try to make a point of saying "Ess-Queue-Ell" because I consider it more correct, and less ambiguous (not just because of the previous query language, but because 'sequel' is a word in common usage, and 'SQL' is not). However, I think I see saying "Sequel Server" as a brand. If I saw "SQL Server" outside of a Microsoft context, my first though would probably be that of a generic client-server RDBMS.
Ess-Queue-Ell all other times.
