I’ve observed climb milling produces slightly oversized parts and oversized holes, which gets worse if the feedrates are high. And conventional milling produces slightly undersized parts and undersized holes.
With a finishing allowance and a finishing pass, neither is a problem but I wish Estlcam could specify climb or conventional milling on a per-toolpath basis (or per-tool would be good enough). Then I don’t have to predict the amount of deflection to set the finishing allowance.
