Need help to choose between two potential braille displays

Hi
Although I'm posting this under the apple section because that's what I'll be using the most for college and work my question is general.
So my focus 4th gen is starting to have problems. Poor battery even after change 2 years ago, some normal braille cells issues... But the main thing is that I had this for about 7 years now. I often use bluetooth and there are frequent disconnects especially on mac. It's micro usb, and it lacks hid braille and built-in basic note taking functions.
I've seen both the bi 40x and focus 5th gen, and the weird boot and shutdown time on the first one. Especially for apple devices, which one works better? I want to have hid braille so already I'm less convinced by the focus, and humanware I know they have very good quality cells. Plus the 40x has some nice features and a micro os like victor reader stream, I asume it could read the nls files? I'm in Canada but there is this aggregate accessible library where we have things from all over the world including nls so...
In Quebec we can choose between these two. Assuming my request is approved, I'd like to have your opinion guys as to which model works best with which os? I use mainly nvda on windows but for school and basically mobility it's always the mac.
Thanks!,
