Amen! I believe on some platforms (MSSQL), joins in the FROM have a
better chance of getting a better query plan and joins in the WHERE,
and possible the query plan can be better cached since two queries
with the same FROM joins but different WHERE clauses are the same
query minus the additional fintering.

Of course, I could be full of it.
