To me it looks like the yahg are more of a warrior race completely, like a Predator..they are highly more advanced than us but all their advances appear to revolve around hunting.

The Krogan seem to be a race that is just angry all the time because of genes, like Mordin says on Tuchanka, Krogan Hospitals were one of the strongest buildings they could make because an enraged injured krogan was only violent.

So yahgs being a warrior race that evolutionary steps lead them into being predator types and krogans being a race that is just angry and fights because of it. Yahg hands down should be able to beat a Krogan.. but if we had to choose Krogans, Urdnot Wrex would beat any Yahg of any day.
