Woods,
not to jump on ya' here, but I've gotta agree with LTLR here on your listing. My standard answer on who makes the best barrel is usually, "depends on what day of the week it is." Not being facetious here, but seriously, regardless of the process (cut vs. buttoned), it really depends more on the care taken by the maker. Both processes can turn out superior barrels if it's done correctly, and both can turn out stainless steel tomato stakes if the manufacturer doesn't do it right. Virtually all of the makers you've mentioned here can turn out some outstanding barrels. I've shot out more than a few truckloads of Harts in routine QC testing over the years, as they were my "standard" barrel. I've set, and still hold, some range records using Douglas barrels on various match rifles. As far as which is best, they're all good, some will turn out an exceptional barrel on a fairly regular basis, but it really just depends on which maker is having a good day that day as to who's the best.
I'd also have worded your comment about gunsmithing a bit differently, though I essentially agree with what you're saying here. No gunsmith can make a bad barrel into a truly good shooter, however, and half-arsed gun plumber can render a truly outstanding barrel into one of the aforementioned tomato stake. Unfortunately, far too many out there are willing to prove my point. Be careful who you trust to assemble your next tackdriver. All the best equipment in the world just makes for an expensive pile of crap if it's not properly put together by someone who knows his business.
