I have owned several Coopers and still own two. I Currently own 4 Fierce rifles and I prefer the Fierce to Cooper. Both shoot great. I really like the magazine of the Fierce over the single stack of the Cooper. I have had issues with plastic tipped bullets jamming during fast cycling during hunting situations (twice) with factory loads in the Cooper. I had to put one less round in the magazine to prevent this from happening. I also like the Fierce stock on the Edge models slightly better. I had a friend purchase a used Fierce on gunbroker and he could not get it to shoot 1/2MOA. He sent it back to Fierce and they confirmed and rebarred the rifle for him at no charge. In all honesty, you cannot go wrong with either gun but since you asked for preferences, my nod goes to Fierce.
