Hello, I've a mix between two X90 and one X95 (and a X80 G5). The only different I see is the additional 2,4GHz cannel and one LAN interface more. In my Mesh the X95 produce a "problem" by the network scanning. I need to optimize the Mesh several times. (But this is not realy a problem by this bandwidth.)

X95 is for sure more recent, it did not exist when I got the X90 time ago. From specs it seems faster. It also has 3 RJ ports, instead of 2.
