I can't speak to the 943's, but in the few times I've used the 853 hyper caps, I haven't been overly impressed. Granted, there could be all kinds of reasons other than the caps - too far from the source, placement pattern not ideal, but in general I think the cardioids are far better, and the omni's are great if you've got the right location to use them.
All that said, one of the best recordings I've ever done was with one hyper cap and one cardioid cap - I was experimenting with something and recorded a show that way by mistake, and it sounded amazing. I think it was just dumb luck.
