Personally I've never found a great deal of difference, but to transform via 
XLT most, if not all, processors load the source into a DomDocument anyway 
so you'd imagine Dom would be better. Most of the development I've done 
doesn't require that degree of performance though, maintainability is more 
of an issue and in this regard XSLT seems to me to win easily.
