Formatting Field - SQL Or Expression - Which Is Best For Performance?

Formatting Field - SQL Or Expression - Which Is Best For Performance?

(OP)
A bit of a general question but curious for all opinions.

I have a Crystal Report I am re-engineering into SSRS 2008.
The Crystal Report has a large 'IF' condition that checks two character department field and then converts the value to a 20 character description.
Clearly this could have been provided better from the data source but I am not allowed to change it.
So I have to do the conversion on my SQL select statement or within an expression.

I'm curious, which is the better practice for performance or does it really make a difference and it's just down to personal preference and/or where the most processing power is available?.
The query only returns 500 odd rows but reads big tables.

Dazed and confused.

Remember.. 'Depression is just anger without enthusiasum'.
