I agree with what OEH. A bad gunsmith doing a bad ream job, crown or headspace work can make a top notch barrel into garbage with one hit of the lathe.

I have had two of the list you have there. And I am going to go with Dan Lilja next go around. My Krieger shoots great, but copper fouls a tad more than I expected from a barrel like this.

My biggest deciding factor last go around was delivery time. I don't think that is an issue anymore. I think sinclair and others have them in stock these days.

Also, if your unsure of the gunsmiths in your area, Shilen, Krieger and i believe Lilja all will chamber and bed your gun. I have heard nothing but good from people that has done this.
