Performance Question - content vs uricontent

The following snippet was taken from Emerging Threats mailing list
discussion regarding optimizing one of the rules.  Can someone here shed
some light into this?

but academically speaking, can anyone say which is theoretically less
load?  For instance, in the below example, which would be faster:
 
        content:"POST "; depth:5; content:"/forms.cgi"; within:64;
(or some other smallish integer to keep from scanning the entire flow)
 
or 
        content:"/forms.cgi HTTP"; depth:69;
 
or
        does uricontent beat them both?
