Nobody knows what you "should" do. This depends on your requirements.

Think about what you need. If you always need the webserver, i.e. if it
is an integral part of your device, then use init + respawn. This way
you are even protected against webserver crashes.
If on the other hand the webserver is an optional service, i.e. there
are times where the service is not allowed to run (for example due to
memory constraints during an update, etc.), then init is not the natural
Because of this optional nature, most services on desktop machines are
not started by init + respawn.
