For that money you get support for a few years.
Plus they hire engineers who know their stuff so you don't see articles like this about avm products: https://www.theregister.co.uk/2018/02/09/netgear_security_patches/
I love them. Just bought my third one (the first one died after a few years, the second one is still working but I wanted the better wifi).
Dead simple, good support (updates even after many years), and just works.
E.g. upgrade to new device: take a backup on the old, many years-old one and restore it on the brand new one. 5 minutes and everything works as before.
