I’ve heard that Clip Studio is pretty close but I have not tried it yet. My experience with Gimp and Krita is that they are fairly close to Photoshop. That is to say that it would be easy for a Photoshop user to jump into those and start working. I have searched for the occasional “how to do XYZ in Gimp or Krita.”

Adobe needs to be abandoned as well. Clip Studio, Krita, Gimp, Affinity are either free OSS or one-time-payment great alternatives without the AI and privacy BS.
