My home office is now converted over to the Surf SOHO router. Better security, a separate Guest LAN for my IoT devices, a backup internet connection to take over during the occasional connectivity drops during the day. Transition went fairly well. I really appreciate the actually helpful Help feature; what a pleasant change from the usual.
One lesson on the Guest LAN: my ST hub would not obtain an IP address from the Guest LAN (assigned to port 1) until the port was classified as an Access (not Trunk) port.
