Nothing wrong with any of those three makers. If they will all make the twist you want then I'd say that they are all about the same. And I have rifles with barrels from each one. Krieger is probably the most expensive of the bunch - and probably the longest turn around time.
When I want a barrel, I look for one of these three, find which ever is available as a blank somewhere in the twist I want and have a smith cut it to shape. The exception being for octagons, in which case, I try to find it premilled.
As far as quality, there are no wrong answers here.
