Audiofeil: True, the B&O cartridges can't compete with the better cartridges that you've named, (I happen to own, and love, the Dynavector XV-1S). But then again, the cost of the B&O cartridges, even adjusting for inflation, is only a fraction of the cost of those cartridges either.
I think a better comparison would be to something like the Benz Micro Glider 2, (another cartridge I've owned recently), and in that comparison, I think the capabilities of the B&O cartridges were definitely in the ballpark.
My two cents worths anyway.
