I know Akira is smoother but I doubt it's 24fps the whole time.
As for your questions, what anime isn't choppy? Hakujaden I guess?
The choppyness is what defines anime style , it doesn't "suffer" at all from it, so of course it doesn't bother me. And anyone who criticizes that aspect is as foolish as someone looking at an impressionist painting saying it can't be as good as a realist painting because it lacks detail.
edit:
See
this video where the CG studio sanzigen intentionally limited the number frames to make things choppier in Black Rock Shooter action scenes when they could have easily chosen to be smoother
