I see there is another thread on the steels now. Take a look and maybe you'll get some helpful info. I don't own any knives in those steels or many of the more recent steels. I am generally going the other way now although I have been really satisfied with M390. Sharpening by hand just takes some practice.... steady hand sort of.

Mostly you just have to pay attention to your angles and the edge as it sharpens and flip from side to side. You can buy guides if you like to use with the DMTs. Take a look at the video on Bob Dozier's web site (Dozier Knives) on sharpening by hand. I have a number of his handmade knives. For the most part, they are lower cost handmades; I call them handmade knives for the working guy. Most are in D-2.
It is sort of fun chasing the super steels, but it is mostly a hobbyist kind of endeavor. I like to try new things, but it is not a focus when buying knives.
