We haven’t test them, so it’s hard for me to say anything about their performance, perhaps someone from community did test them and will be able to prove some feedback.
In any case, you might want to purchase 1 of each and test it in your environment with your content to see if you’re happy with them before committing to a larger quantity.
Regarding cloning installations, in both cases it will probably cause the hardware key to be identical, which means you will need to alter the config file / player options and adjust it so it’s unique - I added a new Player and it went straight to “Display is active and ready to start”? I’m using an imaged/cloned version of Windows and all my Players show up as the same display in the Xibo CMS?

Another thing to keep in mind is, Xibo for Android is our commercial player, which means you will need Xibo for Android licence for each player - £15 per licence, per device.
