Anyone have opinions on the difference? I have carbides for 6.5 and 30 cal. I am leaning towards a stainless for my .223.

not sure of its metallurgy but have been happy with mighty armory 223 small base ..using lanolin alcohol lube very sparingly
 
carbide is harder, it's that simple I don't even know of a stainless brand (doesn't mean there isn't one) but SS will gaul, carbide won't Often I use carbide expander with no lube
 
Once you use carbide you wont go back. It will leave a much better finish inside the neck, wont gall the brass, and requires less or no lube. It will also create less heat which will keep your necks from getting thicker. Set it in ice water or on a cool pad to regulate the temp or by the time your done the necks will be .0001-.0002" thicker than when you began.
