They are definitely "hotter" than a standard primer. I've chrono'd their results along side CCI350 and they give identical result. However, I did have a couple WLPs crack with 44mag loads and I've since switched completely to CCI350. My guess is that the cup material thickness on WLP is a tad thinner to improve sensitivity.
