Hi @cicoub13
So are you going to use these « routers » to do something else?
Personally I don’t want a cloud gateway, no need for an Apple TV (I have a Freebox) but I use a bit of HomeKit via an iPad and iPhone (but not much), no Hue devices.
Aqara M3 might be interesting if you move your Zigbee devices onto it (but expensive).
I didn’t know that site but I have a SMLIGHT SLZB-06M at home for Zigbee, a device connected via Ethernet and PoE, and then connected with z2m.
And the price is more than reasonable.
If I have to switch to a Matter Router, I’d get a second SLZB-06M and flash it with OpenThread.
I haven’t tested with Matter because I don’t have any Thread hardware.
There you go, those were my two cents 
EDIT:
- it seems that matter-over-thread is only the gateway and not the device that provides a QR code to pair, to be confirmed.
- apparently their next dongle SLZD-MR1 will be Zigbee AND Matter over Thread at the same time.
