Been a while since I bought one, Netgear used to be a good balance between cost and not being sh!t.
If it’s more critical business use, could never really go wrong with Draytek – bit more complicated to setup, but not much.
Most modern routers are stable though and if you’re getting drops then it’s likely to be other things causing it, should be easily diagnosed by ISP.
We used to get the odd router fault but not many and usually the ISP side of the network had an 80% good guess rate based on the errors if it was router hardware at fault.
