I have a Shadow 2 Orange, and it's an incredible handgun. The bushing fit is ~ .001 over the barrel diameter. The SA trigger is outstanding and has zero creep in the 2lb. range. I have no experience with the CZC accu-shadow, but I'm sure the accu-shadow has a better DA pull, since the S2 Orange DA pull is at least 8lbs, but it does include two reduced weight mainsprings which I have not tried yet. The hand fitted barrel to slide and and slide to frame fit is outstanding on mine.
