I do both. For batch pistol bullets that don't need to be sized PC is great. I also have a bore riding mold for the .308 that is PC'd and shoots as well as any of my lubed bullets. No, not better, but, just as good. I like the PC on the bore riding portion instead of just lead touching the lands. My other favorite .308 bullet is not a bore rider and it gets run through the lubesizer. It is faster to make up than the multi-step process for a bore rider.
FWIW, I have done some extensive testing with PC and lubed in my .308 and the performance is close enough I can't tell the difference. Consistently under 1 1/2 MOA out to 200yd and under 2MOA at 500yd for both. I get frequent groups near MOA at 500yd, just not all the time
If I were not using a lube sizer I'd get rid of it. Plenty of folks will pay for one, just look at how fast they sell in the classified section. But, I am also a minimalist. If I haven't used something in a year or two I sell it or give it away.
Bottom line is, if you like doing the PC then keep doing it. Doesn't hurt anything and performance is on par with lubed. If you like to lube and not PC then keep at it. No one is making you change.
