I had the same issue, Vally. I have only used CCI, until 2 months ago. CCI primers were nowhere to be found, so I got 4,000 Federal sm pistol. They seem a little easier to seat than CCI. Don't know how they compare to Winchester. I have only shot about 400 so far, but have had no problems. I can definitely tell Federal is softer (firing pin seems leave a deeper indention in the cup using the same powder charge and OAL).
