Looks like there might be a net gain in internal friction, or perhaps it's a wash. Loss of connecting rods is countered by the mass of the cam disk thingie, so there might not be much gain there either. It seems to me that the biggest benefit is that the cam's rotating masses cancel one another, which may make for a smoother running engine. (A six cylinder version would wipe that out of course.)
