Buy the one with the cleanest glass. That makes more difference than anything else.
I have 8 of the 1.8 and 3 of the 1.4
Cleanliness is Godliness.
Bill,sorry but this answer doesn't help much me!...I buy any lens only if it's in good conditions.
I need the best 50 mm,I repeat (i'm sorry...I'm tired too!!!...I'm sorry...I'msorry my friends!) I don't need brightness...I need sharpness,contrast...acutance anything else!!!..This is not a subjective detail, it is an objective detail... It is mathematics:the technical features of any lens are objective,they does not depend on personal taste ...they are equal for all, are universal. It's a picture you get with that lens that is subjectively good or bad ... not the lens in itself...The sharpness,the contrast,the distortion of lens are technical datas that are measured in laboratory scientifically ... not through personal tastes.At least it's my opinion...I hope that you can understand me.I know that write and speak english very bad.i'm very sorry for this.
It would be sufficient only a rapid answer...anything else!...Zuiko 1.4 or Zuiko 1.8...this is the dilemma!
Please don't hate me friends!
There is no BEST.
My answers are based on owing and using these for 38 years.
Sorry I have.no more to offer.
I know that we are frustrating you, but there really isn't a clear answer to your question.

If you do measure those things that can be measured on an optical bench, you will probably find that one will be slightly better at one f/stop, while the other will be slightly better art another.
The later versions have better coatings.
The f/1.4 version gives you a brighter viewfinder. The f/1.8 version is very compact.

My Nikkor UD 20/3.5 should be even crappier, with it's 11 single coated elements (I forget the number of air-to-glass surfaces) but it's also an excellent lens. It's the number of internal sufaces, not the number of elements, anyway.

If stopped down in the F5.6 to F8 realm, the 1.8 and 1.4 render nearly identical images. My controlled testing reveals no advantage one to the other.
I personally reach for the 1.4 because of how the bokeh renders. It's just a little more artsy. Mine are all of the last version made.
I don't think the 50/2 replaced the 50/3.5. The f/2 lens was much more espensive. I have the f/3.5 and it is sharp at every distance and f/stop. If a normal lens will be used closed down and you are yearning for sharpness, get a medium format camera. If I use a Bronica GS-1 with the normal 100/3.5 lens I will expect to get a sharper 8X10, 11X14, 16X20 etc. than any standard lens with a 35mm camera can produce.
There are 5 different 50mm 1.8. Te best one was the last one made: it says "made in Japan" on the name ring. It is multicoated and very sharp. There were 5 different 50mm 1.4 made. The last version is preferred by most. It is multicoated and (I think) has serial numbers above 1,110,000. John
