I've never tried (or wanted to try) thoriated tungsten. I've always just used lanthanated, and it seems to do the job. Last I checked, thoriated was cheaper, so maybe that's a draw for some people. I don't know if thoriated is better in any situations; I was under the impression than lanthanated works just as well.
