The 58/1.4 would be my choice.
Of course everyone has their own motivations, mine are this: I prefer the standard lens for portraits, because I stay quite close to the person and that brings about something more intimate. Much easier to make real contact, instead of sitting on the other side of the room and clicking away . . . to me rather meaningless.
In addition, the standard lenses are small and not intimidating. That helps too.
Minolta's 58/1.4 is a beauty, almost half the size in weight and length compared to the f1.2 version.
