Quit beating it to death, unless you're really interested in the history, then knock yourself out and look for one that interests you the most historically. They will all shoot very well if they are in good condition. If you're interested in fit, finish or stock style, laminated or solid wood, walnut, beech or teak take your pick. Now there is another crux, are you looking for a prewar or wartime or postwar produced rifle. Are you looking for easily available ammo?
If you're just looking for a shooter, all of the rifles you mentioned will be fine. I personally would like to inspect the rifle before buying or at least have return privileges if not satisfied. Just remember, all of the rifles you mention are refurbs and will not be perfect. I'm actually a little surprised at the prices being asked by the dealers. I'm sure they're not gouging, considering their costs, I'm just surprised how quickly they've gotten out of reach for so many people. There can't be very many available.
One thing for sure, you snooze or procrastinate for to long and you will definitely miss out. They won't be available forever.
