Both slow cooking and pressure cooking work well with beef, producing wonderfully tender results. However, there are some differences. If you need dinner faster, the pressure cooker is the ideal method as the meat will cook much more quickly than in the slow cooker. However, if you plan to be out during the day and want to have dinner ready for when you come home, the slow cooker may be more to your advantage. You can simply set it and forget it until you are ready to eat.
