Overall it looks like it produces great images but with consistent PF looks like (I am sure it can be cleaned up in the post very easily unless there are purple subjects in the picture),
I've seen images published in photo magazines with PF. Personally I think people on the forum make way to much of an issue over it. MY wife looks for it, and it upsets her. I ignore it. Once at craft show, she pointed out the PF and CA in a fisheye landscape to a customer. He bought it anyway. He liked the image PF CA and all. Many images with both PF and CA are still excellent images.
I PP on a 27 inch monitor, and I doubt I see PF in 5% of my images. Every lens PFs, even heavily corrected modern designs like the 60-250. So you're looking at a difference of say PF in 2% of your images, where as the 200 PFs in maybe 5. So yes the 200 is more than twice as bad, but it's 2x a very small amount.

I took the DA*200 on my dog walk today just for you.... although I have to admit, I really don't care which lens I take on my dog walk.....
This isn't going to be an IQ decision... this is going to be a do I want a heavy expensive zoom that has faster AF, or a cheaper, lighter older prime with marginally passable AF. I'm not sure you can make this decision looking at images.
I'm not saying the 70-200 isn't better optically, the 200 is a DA* so it could not be a lot better. I'm just saying it isn't a given. It also isn't a given that you'll like it more, even if it is "test chart" optically better.

That depends on how strong your are. The DA*200 is quite manageable, the 70-200 is heavier. Are you going to be shooting only 200mm? Other wise the comparison is puzzling. With my 18-135, the 200 (on APS-c) and a couple TCs I have a complete "do everything" package. If you need to cover 70-200 then your question is answered.
On a K-1, 200mm just isn't very long. I use my 60-250 as a walk around lens on my K-1.
