I also have several. I first bought the oval skew, which works well
and stays sharp for a decent time. Recently bought a 5/8 bowl gouge,
which I am learning to use. I did burn the edge when resharpening,
but that's my technique, I think. Also bought two of the skew gouges,
which seem to be Sorby knockoffs, but work pretty well on pens and
other small stuff.
