I would look on smallnetbuilder reviews as depends on price you're prepared to pay and throughput you want whilst running advanced features like QoS. You could get a WiFi router like an Asus and turn wifi off eg a wired only edgerouter 4 is dearer than an Asus AC86u which has better throughput
I was looking at the UBIQUITI EdgeRouter X 5 Ports Gigabit LAN/WAN Router. It's listed at £50 on Amazon but I wasn't sure if it had all the DHCP, Port Forwarding features I am looking for. Whether it worked with the Hub 3, and of course whether the interface was fast or snail slow like the Virgin Hub 3.
Forgot to mention that I already have a decent Gigabit switch for my wired connections. So my thinking was to simply plug my Gig switch, my BT Whole Home WiFi and the Virgin Hub 3 into the Ubiquiti router. And that's it.
QOS essentially keeps a little bit of bandwidth aside to allow for situations where something is hammering the connection. thus regardless of your maximum theoretical downstream you'll always get less than that when using QOS.
The OP didn't mention QoS so hopefully it's not required. If it is required I suspect it would run at 250 or less but would be interesting to know. I assume you're not running it on yours?
I do have QoS turned on. Hard to tell 100% if it makes a difference but hopefully it does prioritise the kids gaming if we're watching a 4k stream on netflix or prime as they have a very visible impact on latency on the BQM
