Well, if you liked the Nikkor, there's no reason to not like the Canon. Yes, it's a bit slower in the AF department, but still a killer, especially in good light. What I did not like about that lens was the whole package: price/weight/size/AF/MF. I also was bothered by strong longitudinal CA, but all these things are well known, and I don't guess that in your type of photo (good light, medium/long distance) you'll have any problem.
IQ obviously is superb.
