I think distortion can be either flattering eg making eyes big as in the kiddie pics or unflattering eg making ears and noses appear larger, it really depends on the subject and the angles used.
Oh yes, they can both be used. I'm just trying to highlight the differences between the two focal lengths to try and help. Probably making it worse though
