I've found not structCount() slightly faster than structIsEmpty().

Remember that the URL vars are a STRUCT.
You could do:
<cfif NOT StructCount(URL)>
or
<cfif StructIsEmpty(URL)>

EQ vs IS is functionally equivalent.
my personal preference (and it's nothing more than just that... a preference) is to use EQ to compare numeric values and IS to compare strings.
<cfif myVar EQ 5>
<cfif myVar IS "CJ">
i think of it as a little "extra" in the way of self documenting the code. when i see "EQ" i know that my variable is meant to be numeric. when i see "IS" i know that it's meant to be a string.
but there's no difference (performance or otherwise that i know of) between <cfif myVar EQ 5> and <cfif myVar IS 5>.

CJ,
What about 'eq' Vs. 'is'?

the use of EQ vs = is pretty straightforward...
EQ is a comparison operator (if a EQ b)
= is an assignment operator (set a = b)

makes sense... i'm sure i'll still screw it up in my own code for the rest of this millenium, and probably next... but at least it makes sense!
sort of like how some CF tags use EQ and some use =... i'm always getting them intermixed, but when an error page pops up, i know exactly where to look...
thanks!
