I wouldn't really compare pressure cooker pork butt to the smoker version, but it's great compared to the other common non-smoker variant, the crock pot(or slow cooker to be brand generic). For most meats, I don't want to go back to a slow cooker(except for certain sauces/marinades). The pressure cooker version is still tender, but retains more of a meat texture, rather than turning to mush as often happens with a slow cooker.
