All the named makers in your list and many others in the BR game make excellent pipes. They will all supply barrels that properly installed, shooting quality match ammo can drive them in the 2's all day long. If a barrel shoots worse, the maker will likely offer support but chat with them first before buying.
Most of the barrels will shoot in the 1's and 2's on average. That is competitive.
The rare barrel, based more on luck then maker, will shoot in the 0's and 1's. These rare hummers are gems to experience.
Unfortunately, there is no maker then will ensure hummer performance. Big reason why top competitors buy a whack of barrels, keeping the few that shoot best. helps if you have sponsors or really deep pockets.
A barrels ultimate accuracy is determined at time of manf. The most we can do is extract what is there. Lots of effort and money is spent by shooters trying to drop accuracy down that last tenth. About the only thing that is accomplished is wearing out the barrel faster and getting WORSE accuracy.
The best accuracy of any new BR pipe is in the first 500 to 1000rds. If a pipe is going to shoot, you should be able to determine that in the first 50 to 100rds. If it doesn't do what you want, sell it off to a less needy shooter and buy another.
