Does anyone know how iodé compares to /e/OS?

Anyone know whether the Fairphone 6 supports all of the Canadian/North American wireless bands? If I can get confirmation it works with any Canadian carrier I will pay a third party to ship me one from Europe again because I'm so damn sick of having phones with sealed in batteries.

My Fairphone 5 had to be relegated to a glorified iPod Touch because it stopped connecting to my network. And it will probably still outlast my new phone. I will get a new battery for it when the time comes, I still use it at home and it's awesome.

I've not heard of iode. does the installation procedure reolck the bootloader?

Does anyone have experience with both /e/ and iodé? I'm curious to know how they compare. It looks like maybe iodé supports Android Auto, which would be cool since /e/ (which I'm currently daily driving) doesn't. However, it also looks like iodé isn't open-source, which is a deal-breaker for me unless there's some good reason for it that I just don't know.
