I've had better luck with Kennetrek than Meindl, Danner, and other brands I've used.  I treat them a couple times before a wet hunt though.  I treat them first in August during the heat.  I use Kennetrek wax and set them out in the sun all day on the deck.  I bring them in at night to avoid dew and put them out again the next day with more wax if they will take more.  When it won't soak up anymore I quit.  I then wear them on wet conditioning hikes until right before the hunt and treat them again.  When I do conditioning hikes in dry grass I wear my Salomon 4D boots to save wear on the Kennetreks.  
For caribou I used the Crispi Hiland Pro boots with the built-in gaiter.  They kept me dry for a week of the wettest conditions I'll probably ever hunt in.  If I'm headed on a hunt where I'd consider muck boots I'd use them again.  Muck boots just don't work for me if I'm hiking a lot.  I need some ankle support, and even with good insoles they are hard on my feet over time.  I fought plantar fasciitis for a year after wearing muck boots for work to much on a reall wet fall.  I never want to do that again.
