In that size range, and for a beginner, the 3/8 will be a better choice.
My first bowl gouge was a 3/8 Crown, and I've no regrets.

Hi, newbie here...

I'm selecting a bowl gouge, but am somewhat unsure as to the best
width to get. My primary interest is in turning small boxes (8") and
segmented vessels (10") on a Jet mini-lathe. I've decided that a
3/8" or 1/2" would probably best fit my needs. Versatility is more
important than hogging speed.
Which size would be preferable?
Are the Crown gouges OK?
Or are there completely different recommendations?

Thanks,

Greg G.
