My personal opinion is that a grained wood like Oak or Ash look better with limed (aka pickled or cerused) finishes, than other woods with little grain

I use poplar when I want a painted finish that is very smooth, because there is fine grain that does not show with a painted finish. I don't know how it would look with a pickled finished because there is little grain to pick up the finish.

Thank you so much Palimpsest. That would probably be why the words 'Limed Oak' are what I've seen written in the past.
