I personally prefer to talk about specific devices and not operating systems or brands. Each device has different characteristics, even within the same operating system or brand. And, honestly, I believe that each of the current major brands have high quality devices. I leave the "professional" debate to others. As a user (of different brands and different operating systems) I would advise you to choose the one that comes closest to what you are looking for. Of the ones you have mentioned the Onyx Boox I believe will allow you to successfully display any of the formats you normally use. Not that it is better or worse than a PocketBook or a Kindle. It's just that you'll be able to read ePub, PDF and Amazon files without having to do anything special.
