Autobrakes and antiskid are actually valuable indicators in making reports. You should be able to feel the brake releases when antiskid is working. If the antiskid doesn't have to do anything, I call the braking action Good. If I can feel a moderate amount of action, I'll report Medium. If the antiskid is working very hard, and/or there is significant yaw induced because of asymmetrical brake releases, I'll report Poor.
