Which eyepieces work better with a fast newtonian telescope?

I heard that eyepieces that deliver great views in a long focal ratio refractor might perform poorly in a “fast” newtonian.
I heard that eyepieces that deliver great views in a long focal ratio refractor might perform poorly in a “fast” newtonian.
What are the factors that need to be taken into consideration when choosing eyepieces for a “fast” newtonian?
- which eyepiece design works better?
- does the focal length of the eyepiece have any effect on image quality?

My telescope is a 203mm, f=1200mm Dob.
Thanks!
