We keep Moose super short and the slicker is just a nightmare... if your dog is active and you don't do it daily the slicker will be near impossible. At least his has been my experience with a super active dog who also likes to lay on the carpet in 100+ positions and roll around playing with his tale, etc...
We have a poodle / greyhound type brush and I've used that to de-tangle him but rarely need too. We rarely brush too maybe once a week but again we keep him SUPER short.
Like was said before I think it depends on what the cut is what you are grooming him for, etc.
I`m not a prof. groomer so this is all my opinion and experience
