I took one of my RAW file and converted it via Capture One LE with default settings (very low sharpening values) to Adobe space.
I did the same with Breezebrowser and converted to Adobe space with default values (NORMAL for everything, including sharpening).
The differences are subtle. For one thing, even though the capture one software has low sharpening settings (34% with 3 threshold, default), it seems to be at least as sharp as Breezebrowser sample. Also the petals seems to be more brighter yellow. And, the white spance next to the yellow petal is SMOOTH, the Breezebrowser is more "jagged". Here are the samples, they are CROPPED from the original converted files
