I'd disagree. It really does depend on how much use (number of concurrent
sessions etc) is being made of the services. I run a a Pi3B as a home
server that serves DNS, DHCP, imap, smtp, NFS, web, ntp, syslog-server,
ssh, openvpn for our, small, home network - and does some backup stuff.
And it doesn't have swap and runs for months and months and never crashes.

I'd say go for it with a pi W Zero, but watch what happens - and if it is
struggling, then try a 3B. But my guess is you'll be fine.
