for what it's worth I'm on the Bell 3Gbit plan and using their supplied modem/router and it's wifi coverage and performance is great on my Macs, it also supports wifi6e but I prefer disabling on my Macs so that it sticks to wifi6 and has better range, but on wifi6e it will go up to 1500Mbit/sec at around 20-30 feet away.
I have a big house with an odd L-shape, and the Bell fibre optic cable comes into my one end of my house, in the basement. This is ancient history, but when I had their Home Hub 3000, it was just terrible. Range sucked. We couldn't get reliable TV in some parts of house, and at least back then, they told me that using my wired network was not supported.

Actually, you could use a wired network, but their point was that their technical support did not cover that. And then I understood why. When I manually configured Bell's TV boxes for Ethernet, they would work just fine... until a power outage. When the power went out, they'd revert back to the default network connection, which was WiFi... and would fail to connect because the range was poor. This would happen every few months, so eventually I started installing UPSes everywhere.
The other thing that would irritate me to no end is that every once in a while, after a firmware update, the modem would fail to reconnect. What would make it even worse is that they always triggered updates during sleep times (for obvious reasons), but then would fail to connect to the internet, and would not provide me any home phone service either. My wired home alarm system would detect this and then start beeping, waking me and everyone else in the house up. I'd then have to run down into the basement and unplug and replug the power to the modem to reboot it, to finally get it to reconnect to the internet and restore phone service. It was just a disaster.
And then when it came time to renegotiate after my promotional deal expired, they would have the gall to try to raise my prices $50-70 a month and say it was a decent deal because it wasn't full retail pricing.
The hardware is better now, but they still have the requirement to use VLANs just to watch TV. It'd be easier to manage if I didn't have to get TV service though.
