Filterstage as good performance compare to Trans..

That statement does not hold true for versions 7.5 and higher.

In A Filter Stage- You cannot use Transform functions on a field and derive constraints based on the result.

But you could possibly use a Transformer stage constraint for almost any kind of Filter that you can set in a Filter Stage.

Filter stage uses an SQL-like WHERE clause.
Switch stage uses a value.
Transformer stage uses a BASIC-like expression.
