I am far from an expert but I'll give my opinion. For a cow permit I would pick a St Helens unit and get to know the road network. All of the St Helens units should provide opportunity with a little homework.
For bull my first choice would be Margaret, this may be dependent on access. My second choice would be White River. One thing you should know about the WR unit is it's not for the faint of heart, it is amongst the steepest, nastiest, and rugged units in the state (non tree farm disclaimer). Third I would go with Nooksack spike, you are limited to spikes but it's close to a slam dunk.
For quality I would go with any of the rifle rut hunts (the unit you are most familiar with being best). Second I would go with Nooksack.Third I would go with Toutle, that being your best chance at drawing with the least trophy potential.
I would change my order in accordance with my desired hunt.
