I have one of each but hard to compare ergonomics as the H.S. is on a Model 70 Heavy Varmint and the B&C is on a Model 7 lightweight.
I do think the grip of the B&C is on the thick side for a stock on such a lightweight sporter. The H.S. is by design being a heavy varmint stock so can't speak to their sporter design.
Fit and finish I don't see much difference and I was happy with the quality of both. Again, not a large sample.
I bought the B&C from Redhawk Rifles as well and was very happy with that experience.
I also have a couple of McMillans and there is no question they are at a different level. If money or time was never a factor I would buy the McMillans every time. If I don't want to put $500+ into a stock I would use either an H.S. or B&C again.
