Best legacy 50 f1.4 prime

I have both a Minolta MD 50 1.4 that I originally bought when I first got a NEX and a Minolta Rokkor MC 50 1.4 that I picked up a year or so later as it was a real bargain I couldnt turn down. Both are great lenses and would recomend them both but I havent used either enough to determine which I prefer. I need to make a decision soon though I as I need to sell a few of my lenses to afford the SEL35
