Pictures shot at a shallow depth of field, ie, lower aperture of 2 or below, are really good at separating the subject from the background. The separation of the subject from the background is what makes the picture attractive. And whenever you focus on a person the focus point is the eyes. You don't want to have the eyes out of focus. As long as they are in focus even if other parts of the face are slightly blurred it will look great. So if you focus on the eyes at a shallow depth of field then those shots will be okay. It won't be as hard to focus on the eye for a portrait because the subject is posing. I always try to shoot the subject with the lower F value as possible. Especially if you are taking full body shots. If its only of the face, you can go upto 2.8.
And having full frame for portraits does make a difference. With a full frame to get the same field of view you will be closer to the subject. Since you are closer to the subject, the same F1.8 or 2 will give a better background blur. Its not the full frame body itself which gives you better blur. Its the field of view which you get using a full frame. And a full frame captures more light and there fore will have a better dynamic range allowing you to pull more detail from shadows. Once I moved from APS-C to FF I honestly can't look back ..
