Ours is a Tatonka and it's been great. Time to sell it actually so thanks for this topic as a reminder
A tip for anyone looking for a child carrier - don't get one that is just a seat with a detachable bag underneath, unless you're ok with the detachable bag swinging as you walk and whacking you in the kidneys.
And definitely get one that has the fold-out prop to stand it up - and be sure to try it on before you buy and work out how to extend the prop and get it off your back and onto the ground, without losing the child on the way. You'll also need to be able to load the child then get the thing onto your back solo, again not super easy and another reason why mum will probably pass on using it. And never leave the child unattended in it when it's on the ground as they can wriggle enough to risk folding the prop in and then over they'll go. Even more of a risk if they can get their feet to the ground.
All models take their toll on the wearer, it's surprising how heavy an infant/toddler can be. As was suggested above, mum won't carry it much, it's pretty much a dad job - the shoulders take quite a load on a decent walk.
But they are great things if you like a wander in the bush, and bub will love it.
