In case anyone was interested, I tested the DG 500 Super and metz 48 at 1/1, and the 500 Super is indeed more powerful.
the metz 48 did have a significantly faster recycle time, but then again it was less powerful and I don't have a good way to test the same power recycle times.
Also, the 500 aims the AF assist notably above center, and perhaps as a result, the K-x struggles in dark with it, while the metz 48 works quite well. And the Spot beam mode (af-assist only) is useful but the sigma does the same thing in iso adjust mode.
The Sigma has multi mode, though.
