I would want the best accuracy reasonably possible. To me that means a scoped gun...... so the tracker is out.
I also believe that as a general rule pump guns are not as accurate as bolt actions or single shots........so thatrules out the Mossberg.
That leaves you with theUltra.

Wouldn't be my choice, but out of those three I think it is the best.

Not to make the decision harder, but this should at least be another consideration....used Savage 210...325$
