Helios 77m-4 or Helios 44-2?

Question

I love swirling bokeh, its the main reason I want to buy one of these lenses. The Helios 77m-4 seems to have more swirl in its bokeh, but the Helios 44-2 may be sharper. The swirling bokeh is the main reason I want to buy one of these lenses. So, the question is: When it comes to sharpness and abberation, which lens is better in quality?

Update:

50mm 1.8 lens kinda sucks for canon, no thanks
