I think the trade-off you make with mythtranscode vs. nuvexport is:

	- Ease of use (you would have to configure nuvexport into a
	  user job).
	- Speed (last I tried, mythtranscode was faster).
	- Quality for a given filesize (last I played with it, the
	  various things available with nuvexport give you much better
	  quality transcodes). I don't know exactly what codec is used
	  by mythtranscode, but my configuration yields worse results
	  at bigger filesizes when compared against similar content
	  found on the web encoded with XviD, etc.

For me, I choose mythtranscode for ease of use and its integration
with MythTV. I'm sensitive to filesize (but not too much, since I
watch and delete), and don't care too much about quality.
