'Certainly a good question & I don't think the answer's the same for all faces. One school might preach that regardless of face, lay of the beard - a skilled person should be able to do any stroke on all places. Even a few successfully do the 'fool's stroke (atg moustache). Another school preaches atg isn't necc.
With this and similar questions, its helpful not to lose track of the original objective - close, comfortable, preferably enjoyable. Is it necc. to have pro-level skills to shave? Hell no. One thing I really love is Lynn's enduring dictum: have fun. Go ahead & try to improve skills. Because we do it daily (most), it'll probably happen whether or not we try. If the challenges give too much carnage or irritation - no need to make it a life & death battle - get back to 'fun' until you get the itch for challenge again. I have to say/remind myself of this, 'cause I'll get in acheivement ruts like anyone else.
