is slower it's only one hundredth of a millisecond difference i.e. way below
anything I'd worry about. So it's a style thing then.

You may get these results due to use of de(), run this code, which I think
is more fair:
<cfset temp = getTickCount()>
<cfoutput>
<cfloop index="i" from="1" to="10000">
<cfif i mod 2>1<cfelse>2</cfif>
</cfloop>
</cfoutput>
<cfoutput><h1>#temp-getTickCount()#</h1></cfoutput>
<cfset temp = getTickCount()>
<cfoutput>
<cfloop index="i" from="1" to="10000">
#iif(i mod 2, 1, 2)#
</cfloop>
</cfoutput>
<cfoutput><h1>#temp-getTickCount()#</h1></cfoutput>
I got 15 - 16 as results for both of them with some variations both ways
which I discard as noise.

Subject: RE: Which is quicker
My test indicates iif() is about 400% slower. But the real issue is code
readability. If you think it's more readable in any or all circumstances,
I
say go for it. Personally, I think this example demonstrates it is less
readable. There are probably other example that show it in a better light.
Here's my sample:
<cf_stopwatch>
<cfoutput>
<cfloop index="i" from="1" to="10000">
<cfif i mod 2>!<cfelse>?</cfif>
</cfloop>
</cfoutput>
</cf_stopwatch>
<cf_stopwatch>
<cfoutput>
<cfloop index="i" from="1" to="10000">
#iif(i mod 2, de("!"), de("?"))#
</cfloop>
</cfoutput>
</cf_stopwatch>

I don't know why people don't like iif (immediate if), it is as quick as
cfif and takes only one line. For simple things, like "if x < y print true
else print false", I think using iif makes code shorter without
sacrificing
clarity and speed.
If you don't believe iif is fast then I encourage you to write a small
test
and see for yourself.

cfswitch is both quicker and more elegant. The only downside is that it
doesn't handle dynamic values.
Iii() is one of those functions, like evaluate(), usage of which is
generally discouraged.

Subject: Which is quicker
Can I get a little advice on which is quicker or which is the preferred
way
of programming - there are 8 items to select from:
CFIF, CFCASE or IIF
TIA!
