have had both too
the 50F1.8 has the worst bokeh I ever saw, worst than the kit EFS 18-55.
it is sharp at f2 only if you manage to focus correctly, the autofocus acuracy of this lens is dreadful on several samples.
OTOH the 50f1.4 is not that sharp at f1.4 but I don't agree here at f2 it is at least as good as the 50F1.8 with a more reliable autofocus.
i found no serious optical flaws with it
its only con: its autofocus, this lens has an old micromotor USM, its lifespan is short.
btw if you're getting this one you could sell the zeiss (unless using it for macro) since beyound f2.8 almost nothing is sharper than this lens,
my experience tells me manual focus in concerts at f.4 is a very bad idea, try it if you don't believe me
