Funny you mention the 24 and 20 mm FL. I found the 24 usually very precise in focus, Nikkor or Sigma didn't matter much. But the 20/1.4 is a challenge to AF with Phase detection. It's either the lens or the realtion between distance and focus area. To me it appears that with 20 mm there are just enough obstacles in reach to become potential focus targets.
And the turning angle of the focus ring is much larger with MF lenses, true, but I prefer the geared drive of manual focus of "normal primes" - to me, precise enough.
