My $0.02:

Use literal result elements when you can; use xsl:element when you have to.

You have to use xsl:element when:
 * The element name is being generated dynamically
 * You are developing in a framework that doesn't like LREs
   (maybe it's validating the stylesheet against a schema
    with only the xsl elements in it)
 * You are doing something funky involving names and/or namespaces,
   such as stripping namespaces.

... and there may be one or two other reasons.

I find LREs much easier to read and maintain. LREs do have a 
pedagogical downside, as beginners sometimes interpret them as 
meaning the processor  does "tag writing" (which it doesn't). But the 
real fix for that is not to avoid them, but simply present a good 
demonstration of how tag-writing isn't what's happening (for example, 
showing output of empty HTML elements with output method="xml" vs 
method="html").

Cheers,
Wendell
