SQLAnywhere: Watcom SQL or T-SQL

The general question. I am developing for Sybase SQL Anywhere 10. For backward compatibility purposes, almost all of our stored procedures are written in Transact-SQL. Are there any advantages or disadvantages to using T-SQL instead of the Watcom dialect?

If you are ever trying to migrate to SQL Server (or you are going to work on SQL Server), Sybase T-SQL is very close to the T-SQL SQL server. Sybase and MS came together during the day, so the core of these languages ​​is very similar.
