I think Orijen and Acana are definitely above TOTW in terms of quality control, production, company, etc. TOTW is a Diamond food which some are uncomfortable with. I prefer Champion since they manufacture their own food. With that said, if your dog does terrible on Orijen, but does amazing on TOTW, then obviously TOTW is a superior food for you and your dog.
I prefer Acana over Orijen though - I'm just not sure if the richness, very high protein of Orijen is necessary for most pet dogs. It seems like it may be a bit TOO much of a good thing for some dogs. After a few months of feeding lower protein/lower fat/grain inclusive foods to Jackson, I noticed a big difference once I started Acana again. He ate Acana for over a year, we did a few months of TOTW, then he had a little GI issue (due to somethng else) so we switched to the lower fat foods for a bit, but are on our 2nd bag of Acana again. His hair is softer to touch, shinier, not as dull (he had also started 'shedding' a bit and he's a non-shedding dog, since back on Acana - no more!), I can see more muscle tone on him, poops are good - he gets the occasional soft poo while we are on walks but only on walks and he's always done this, so I dunno.
Anyways I love Acana. I don't think it's any worse than Orijen, in fact sometimes I think it's better, and it's cheaper. So it works for us. I plan on keeping him on this again, as well as trying their new formulas coming out (grain inclusive) and then also adding Fromm grain-free into the rotation.
