No way to know without trying both mics on the voice you are recording. But the 4050 also gives you multiple patterns. Given the difference in price, chances are you're getting a lot more for your money with the 4050.
Of course, all the features in the world won't amount to squat if it just so happens that the KSM32 sounds better on your particular voice. That's why there's NO SUBSTITUTE for trying the mics yourself. See if you can buy both and return one. Or find a couple you can borrow and compare.
