Mattdeere,
I am familiar with the country you are describing. Both are decent general season areas. But since the Commissary ridge area is over 20 miles long, there are lots of areas with elk, and just as many if not more without elk. Elk aren't behind every tree. These units have a strong population (extra cow tags available) and an ample supply of hunters. Success ratios are good for a general season unit, but you won't shoot many elk driving down the road. The country is steep and generally heavily timbered, but with open hillsides as well. Count on having to burn some boot rubber to get back to the elk. Horses are used heavily in these units to access the back country. Coantag creek is a particularly rugged area and many miles long. You pretty much have to backpack into this area, as you are several hours of hiking from any road. Not an area I would recommend for rookies, but you don't mention your experience elk hunting. You also don't mention what you are looking for. If any bull will do, you should be fine in this area, and if you are willing to kill cows so much the better. It isn't considered a trophy area by any means, and certainly not by WY standards. But there is good hunting if you are willing to work.
Good Luck.
