If buffalo are more than a fantasy hands down the 45-70. The others are in a different league although the 444 can be loaded up quite a bit. The 45-70 can cover all the same bases and more with reloading. The only negative is if you wanted a short light rifle, carbines are available for the 45-70 but they make the hot loads not much fun. Depends on the platform but from your other lever choices looks like you like the traditional ones. There are a lot of choices in 45-70.
More than the other two but the 44 will be close in number of rifles offered the 444 not so much.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
