Question regarding Spanish publishing houses

I’m interested in Spanish publishing houses. I’ve searched quite a few websites, but I can’t find any that tell me which ones compare with the major European ones.

Of the following Spanish publishers, which one would be on a par with Oxford/Cambridge, Duden or Larousse:

Planeta, Aguilar or Espasa ?

I look forward to your feedback.

It’s probably
Real Academia Española.
