The 50 1.8 II is the superior and more reliable lens.
I would hazard a guess that you are in a minority with that position. The 50 F/1.8 is sharp and a stellar value, but it lacks virtually everything else.
As much maligned as the 50 F/1.4 is, the 50 F/1.8 has greater issues. Pentagonal bokeh, cheap build and a comically slow (and noisy!) focusing plague this lens.
It's a great starter lens in getting use to primes, using larger apertures, etc. but unless you are shooting non-moving objects at stopped down apertures, I'd choose the F/1.4 ten times out of ten over the F/1.8.
I've owned both lenses. The 50 1.4, is, quite frankly, a piece of garbage. The 50 1.8 II has a deceivingly better build in real world use, IMHO. the 50 1.8 II is actually sharper to boot, and I found the focus to be more reliable.
