Is Pan 14-45 sharper than 14-42 or PZ 14-42?

I had the 14-45 on the G3 (I never had the 14-42 kit lens, which was generally regarded as inferior to the 14-45, and certainly feels much cheaper in construction) and compared it with the 14-42x.  The 14-42x was slightly sharper at 14mm and a bit softer at 42mm.  Since I use the short focal lengths much more than longer ones, my preference overall was for the 14-42x, and I liked the smaller size.  I traded in the G3/14-45 on a GX1/14-42x for very little difference in cost.. I now use the 14-42x on the OM-D, and it works even better than it did on the GX1.
