They are all good rifles. What are your priorities? What kind of shooting do you plan to do? How much do you want to spend and how long are you willing to wait? How important are historical authenticity and USA manufacture? As you have noted, not all models and options are available from each of these companies.

Viewing manufacturing operations may be interesting, but not particularly germane to a decision as to which of these rifles to purchase. JMO.
