It will be hard to find someone who actually purchased both devices in order to be able to compare them. These are not exactly cheap, to begin with.

While not owning any of both either, i am using the predecessor of the Mimas, the Likebook Note, and used Onyx Boox devices before. Based on my limited experience with both, i'd rather suggest going with Onyx Boox, no matter what.

Hardware features are nice and all, but if the included software and the expected support are not able to hold the promise of such an expensive device, then it all quickly boils down to Onyx Boox.

Likebook appears not to be able to deliver software wise, the Note i use would hardly be capable for it's intended use without 3rd party software (koreader, goldendict, Librera).

During the same time people in this forum keep speculating about firmware upgrades, enhancements, and bug fixes by Likebook, Onyx Boox has already published multiple updates and fixes. That alone is worth preferring Onyx Boox.
