Which one is "better"? The Krebs is 100$. The DPH is 45$ but then Ill need the VLTOR adapter as well to run a standard AR buttstock, which is another 80$. The VLTOR will have to have a date with the dremel to fit into the DPH, which I'll do, but is not "ideal".  The Krebs appears to just accept a buttstock tube directly. Anyone have anything to say about these parts? What did you get and why?

Krebs also need some cutting to fit vepr. At least in my case. But overall I am pleased with quality.
In my humble opinion and esthetically speaking installing ar15 stocks on AK is the same as installing AK stock on ar15. If you know what I mean.

You can't go wrong with krebs. review here
