I like both VG10 and ZDP-189. VG10 should not be thought of as a "budget steel".
Everyone who says ZDP-189 excessively rusts are completely over exaggerating! (I almost recently started a thread on this...)
I soaked one of mine in various forms of vinegar for hours just to test it, and it didn't do much other than darken the blade, barely perceptible in certain angles of light. I even left it covered in rice vinegar over night once to dry and no effect. And, this may have actually protected it because now it won't rust. I even stir my coffee with it often. Cut tomatoes with it and left it for hours without cleaning....
Just treat it well and care for it and you'll be fine. These people complaining of ZDP-189 rusting must have a heart attack with Super Blue, or 52100, or even M4, etc...
Also the sharpening I haven't found much harder at all than any other high end steels. Maybe serious reprofiling... but I actually enjoy some good therapeutic sharpening sessions.
Here's a couple of photos for the haters who keep spreading words of exaggeration.
This is me TRYING to get it to patina, but even after left to dry, it just wiped off clean, several times of doing this...
