I'm not convinced that I would choose Merlin, because it only supports a very limited amount of devices. However, I had Asus routers in the past and they were not half bad.
If you don't need USB and could switch to OpenWRT, you could go for a Netgear WAX 202 - I got a used one for 50 bucks, pretty stable so far. Or maybe a TP-Link AX 1800 for 60 bucks new.
Again, I very much agree with you, very sound advice. The reason I stick with merlin/Asus is that I do not want to spend too much time, I want to buy sth, configure/deploy/forget.
