You’ll get used to it eventually
I’ve been earning my living mostly with connecting to remote systems via ssh (and other means) for quite a few years and I still occasionally mess up and enter commands on a wrong terminal. Less now than I used to, but it still happens. The trick is to learn youself to pause for a second and confirm the target for any potentially destructive or otherwise harmful command, no matter if it’s locally or to some server other side of the world.
I somewhat agree on your comment about documentation and UI (altough once you get used to it, it’s manageable) but just to add with my experience on these things: for me they’ve been rock solid. I’ve used them both at home and professionally (mostly on small-ish networks) for at least 10 years and they just seem to run just fine.
Currently my home router is RB4011iGS+ and there’s been absolutely no problems with it in the 4-5 years it’s been on my network. I’m not saying all their models are as reliable and there’s not that many models I’ve had my hands on, but my experience with them has so far been pretty good.
