If you want me to recommend a
specific router/network appliance for you, I'd need to know your exact requirements first. ("Nothing special, just an ordinary router" does not cut it; I need specifics.)
The
OpenWRT One seems particularly interesting for us meddlers; if not for anything else, for supporting the OpenWRT project.
I usually do the reverse: select between a limited number of options available to me. Customer protections are quite strong in Finland, so I prefer to buy new hardware locally if possible (so I can return them without a hassle if I get a b0rked unit), but the selection is quite limited. I check out each possibility, using
OpenWRT Table of Hardware, and read the device page noting limitations and unsupported features in particular. Starting at the
OpenWRT buyer's guide, and checking the available devices in your price and feature range against the OpenWRT ToH, is your best bet.
I do not have any specific models I personally like, because they
all have their downsides; better just pick one that fits your specific use case the best. I personally also add custom hardware on top (especially display modules via USB control for status display for non-technical humans), and customized firewall stuff (mostly to stop the annoyance of port sniffing and bot attacks), so I tend to look more for network appliances that can perform the duties of a router. I also like to use OpenVPN (community/open source) for remote connections inwards, so the router being able to support that with sufficient bandwidth is nice. Benchmarked, not just listed in sales materials.
I also do not trust any specific brand, I look at individual devices. Even the model
revision matters, because the manufacturers can switch even SoC families between revisions. If you trust a vendor, or a model, be prepared to be disappointed.
As a practical approach, I do recommend you consider routers with full OpenWRT support, but with stock firmware you can also accept. That way, you
know you can use the device, even if you switch to OpenWRT. OpenWRT isn't some magic hammer either, and it does have its own quirks; but, being open source, just gives you an opportunity to fix those quirks (or get somebody to help you fix those, depending on whether you pay or find someone with enough interest). No free lunch, I'm afraid.
