Which tool to use for developing Pl/Sql on MySQL?

[alba\.albetti]

Hi,
beginning to work with MySQL I've found there exist two similar tools for browsing the db
and developing in Pl/Sql and they are SQL-Front and MySQL Query Browser. Fot not wasting
time in learning both can anyone tell me which of these is generally used wordwide? So I
make practice with the most used one.

Thanks in advance!
