Moose have really elastic hides that like to catch a soft bullet on the off side. I really like 2 holes on big game, and your guide will too! in the off chance of a poor shot, the TSX is going to break bone better, and give you a greater chance at a pass through (blood trail).
Moose have a great capacity to retain their blood unless you can get them to help pump it out. The best blood trails originate from the nose and mouth on these critters, so souping the lungs is the ticket. Of course, any bullet works for those shots, so even an Interlock or PRVI bullet will do the trick nicely. Either of the bullets you propose are plenty.
